.22-250 Remington — The Classic Varmint Cartridge

.22-250 Cartridge DiagramA bona fide 4000+ fps varmint-slayer, the .22-250 is probably the most popular mid-sized cartridge in existence. First wildcatted in the 1930s off the Savage 25-3000 parent case, the .22-250 is widely used throughout the world, and all the major rifle-makers chamber for this fast, versatile cartridge. Though it was popular for decades among varminters, the .22-250 really took off when Remington standardized the cartridge in 1965. Now, in any large sporting goods store or gun-shop, you’ll find a wide selection of factory ammo with bullet weights from 35 grains up to 75 grains. And the .22-250 is far from “old hat”. Just this year, Hornady introduced .22-250 SuperFormance ammo that achieves hitherto unheard-of velocities with 50gr bullets. Though used primarily for varminting, the .22-250, with the right bullet, can be a capable deer-hunting round, and it has been used successfully in High Power competition.

22-250 Terry Wieland.22-250 Cartridge History in RifleShooter Magazine
If you shoot a .22-250, or are just interested in the history of the cartridge, Peterson’s RifleShooter Magazine offers a fascinating article by Terry Wieland. The author explains how the .22-250 was developed in the late 1930s and was initially known as the .22-250 Varminter. In 1963 the round gained popularity when Browning chambered it in a production rifle — even before factory-loaded ammo was available.

Then, in 1965, the round became “official” when Remington standardized the .22-250 with “Remington” added to the name. Remington produced .22-250 Rem ammo and sold Rem 700s chambered in the “new” cartridge. Once Remington got involved, the round became hugely popular. According to Wieland: “Overnight, it seemed, the .22-250 established itself as the dominant high-velocity .22. Winchester had just discontinued the .220 Swift and replaced it with the oddball .225 Winchester, a rimmed cartridge that was gone in less than a decade. Everyone ignored the .225 while falling over themselves to chamber the .22-250.”

.22-250 Recommended Twist Rates
223 Rem Remington barrel Twist rateThe .22-250 shoots a wide range of bullets very effectively, from 35gr flat-based varmint bullets, to ultra-long 90gr VLDs. However, you’ll need the right twist rate for your choice of bullet. For max velocity and accuracy with the lightest bullets, a 1:14″ twist may be ideal. More versatile is a 1:12″ twist that will allow you to shoot the popular 60-64 grain match bullets. For normal lead-core jacketed bullets, a true 1:9″ twist will let you shoot up to 75gr bullets (except some longer VLDs). The Hornady 75gr BTHP shoots very well in a 9-twist .22-250. Since most .22-250 Rem shooters prefer bullets in the 50-73gr range, a good “do-it-all” solution is a 9-twist.

Overall, what twist rate is best? For all-around use, including 500-600 yard ground hog matches, we like a 9-twist. That will let you shoot some pretty-high-BC bullets at long range without “choking” the lighter bullets too much. If you don’t plan to shoot at long range, a 12-twist barrel will do the job. The slower twist will give you a bit more velocity, and minimize the risk of jacket failure at high rpms. That’s one reason why the majority of factory .22-250 rifles are sold with 1:12″ twist barrels. Savage does offer some 9-twist barrel options. That’s nice if you shoot in windy conditions and need to stabilize a longer bullet. If you plan to use your .22-250 for across the course (high power) competition, you’ll want to use the 77-80 grain boat-tail match bullets. For those, we suggest an 8-twist barrel (as long as it is a true 1:8″ twist). That will let you shoot the excellent 77gr and 80gr Sierra MatchKings, and 80gr Bergers.

.22-250 Remington Components–Brass, Powder, Primers

.22-250 Brass
With Lapua now making .22-250 cases, shooters now have a clear “best choice” for .22-250 cartridge brass: Lapua. Though Norma-brand .22-250 brass is also very good, the new Lapua brass is even more consistent, and it is stronger. You’ll find, after multiple reloadings with stout loads, that the Lapua brass is still good to go, while other brands of brass may exhibit loose primer pockets. Like Lapua’s 6mmBR brass, the new Lapua .22-250 brass is now the standard by which all other brands of .22-250 brass are measured. If you can afford it, buy the Lapua, confident that you are getting the best .22-250 brass on the market today.

Forum member William P. (aka “Heath”) just got two boxes of the new brass. Both boxes have the same lot number. Heath was kind enough to sort the brass and report his findings.

Lapua 22-250 brass

Based on Heath’s 200-count sample, we can say this new brass is very, very consistent in weight. The total weight spread (delta) for 200 cases was just 1.4 grains! And the vast majority, 83%, were within 0.7 grains in weight (160.3 – 161.0). For the varminter, sorting may be superfluous. Lapua delivers a very consistent, high quality new product, and we love the new, blue plastic boxes.

After Lapua, what brass should you buy? As noted, Norma brass is very good, but it normally costs more than the Lapua brass so there is no real advantage — unless you already have a supply and want to keep things consistent. Among domestic manufacturers we recommend Nosler, Winchester, Remington, and Federal brands in that order. Some people say the Winchester brass is more durable than Nosler. Other folks have suggested that Nosler actually IS weight-sorted Winchester, but we can’t confirm that. If we used a .22-250 rifle in “run and gun” tactical matches where we inevitably lost a great deal of brass, we would substitute Remington for the Lapua brass, just because it much, much cheaper.

The .22-250 is a versatile cartridge, commonly used to shoot everything from 35gr frangible bullets to 80gr long-range match bullets. Because, relatively speaking, the .22-250 is an “overbore” cartridge, you’ll want to use powders that are a class slower in burn rate than you might use with the .223 Rem or 22 BR. Using a slower powder can, some folks believe, also extend your barrel life — but how you shoot is just as important to barrel life as is powder selection. Avoid sustained rapid firing, allow your barrel to cool between shots, and monitor barrel fouling. Build-up of carbon and copper fouling can increase barrel heat and pressure.

Because .22-250s are commonly used in the varmint fields on hot summer day, you’ll want to choose powders that are not overly sensitive to hot temperatures. Hodgdon’s Extreme powders are good in this respect. These are extruded (stick) powders, however, and if you load with a progressive press such as a Dillon 550, the extruded powders may not measure as smoothly as ball powders such as H414.

For the light 35-45 grain bullets, H414, IMR-3031, and H322 are good choices (though there are many others). For the 50-60 grain bullets most commonly used in .22-250, you have a huge selection of good medium burn-rate powders, but we like the new IMR-8208 XBR powder and H-4895 because they deliver great accuracy and they are not temp sensitive. If you plan to shoot the heavy 75gr to 80gr bullets (and you have a barrel with appropriate twist rate), you’ll need a slower burning powder such as H4350, H4831sc, or Ramshot Big Game. Vihtavuori N550 has been popular with guys who shoot the 75gr to 80gr bullets because it yields excellent velocity. However, N550, a double-base powder, is much more temp sensitive than H4350.

22-250 LapuaPrimers
The .22-250 uses large rifle primers. There is no one “perfect” LR primer for the .22-250 cartridge. The optimal primer choice depends on numerous factors including powder, bullet, brass type, seating depth, load density, and even your gun’s internal barrel dimensions. That said, if you are shooting a factory rifle, such as a Browning, Howa, Remington, Savage, or Winchester, we recommend starting with CCI-brand primers. CCI primers boast harder-than-average primer cups. Factory rifles have ample clearance around the firing pins. This can promote early primer cratering even when pressures are below rated max. If you use a primer with a soft cup, you can get extreme cratering, or even a pierced primer when running stout loads. With their hard cups, CCI primers won’t crater as much, giving you an extra margin of safety.

Russian (Wolf and Tula) primers also have fairly thick cups and these can be a good choice too. The Russian primers are relatively inexpensive and they have a good reputation for delivering good accuracy with low ES. However, there is a down-side. The Russian primers tend to require more seating force to seat properly, and we have observed the occasional quality control problem — a primer that is dimensionally off, or a primer that simply fails to ignite on the first strike. If you’re in the National Championship, that’s a big deal. If you’re on a varmint hunting trip, shooting hundreds of rounds a day, Wolfs will probably work fine.

When tuning your loads, don’t hesitate to try different brands of primers if accuracy or velocity is disappointed. Primers do make a difference. We have seen some rifles exhibit significant accuracy gains when switching from CCIs to Federals or vice-versa. Likewise, when moving from one brand of bullet to another you may want to experiment with primer types. Also note that while your powder may be insensitive to temperature changes, your primers may not! This point was explained to us recently by Chris Hodgdon of Hodgdon Powder. He explained that a powder which shows very uniform velocity over a wide temperature range may perform worse with a different brand of primer. In tests with Varget powder in a .308 Win, Hodgdon found Winchester primers helped minimize temperature-based variations. A Hodgdon technician told us: “We use the Winchester LR primer for this test because it shows little to no sensitivity to temps. The next least sensitive is the Federal 210M, but it does show some movement.” This comment applies ONLY to Varget in a .308, but it does illustrate the point that primers as well as powders, can be temp-sensitive.

Bullet Choices for the .22-250 Remington and .22-250 AI
There’s a huge selection of .224-cal bullets for the .22-250 Rem, ranging from 35 grains all the way up to 90 grains.

22250 bullets

Varmint and Hunting Bullets
On the light end, the modern 35-40 grain varmint bullets are designed to survive very high RPM, and then “detonate” explosively in the target. Among these you have the composite-core 36gr “Varmint Grenade” from Barnes, and the 40gr Hornady V-Max and Sierra BlitzKing offerings. These work well on varmint-sized critters, and usually don’t exit. Watch the explosive effect of a “Varmint Grenade” launched at 4344 fps in this High-Speed Video Clip. Barnes explains: “The bullet’s copper-tin composite core is highly frangible. The new bullet fragments explosively [inside] ground squirrels and prairie dogs. The bullet blows up completely at high speed, creating little or no exit wound on larger animals.”

Among the heavier, standard “hunting” bullets that are effective on larger game, Sierra offers its 65gr Game King, and Nosler its 60gr Partition, and Barnes has its Triple-Shock” X-Bullet in 53, 62, and 70gr weights. The 70-grainer has good penetrating ability on medium-size game, but it requires a 1:9″ or faster twist to stabilize

.222 .223 Bullet Cartridge

Light-Weight Bullets
For close-range competition (100-300 yards) one can find a large variety of 50-53gn Match bullets, both custom made and commercial. The Sierra 52gr BTMK is a popular “short-line” load with Highpower shooters. Custom 52s in .224 caliber are offered by the benchrest bullet-makers, such as Bart Sauter, Lester Bruno, and Don Gentner. Lester also makes a very accurate 57. We’ve had very good luck with Bergers in the 50-65gr range. Berger offers a panoply of options, with Berger FB bullets offered in 50, 52, 55, 60, 62, and 64-grain weights. This wide selection lets you literally “pick your BC”, from .241 for the 50, to .306 for the 64 grainer. If you’re looking for do-it-all bullet that can shoot bugholes on paper and also perform in the varmint field, these Bergers will fit the bill.

Mid-Range (300-600 yard) Bullets
For the mid-range varminters there are even more options available in the 68-80gr weight range–many illustrated on this page. Check out the 69gr Lapua Scenar (.321 BC), 75 A-Max (.435 BC), and Berger 75gr VLD (.447 BC). Some guys have asked us: “Please don’t tell people about the 75 A-Max. Right now these are super cheap, and they shoot like a house on fire.” The A-Maxs are indeed a major bargain. Midsouth Shooters Supply sells the 75gr A-Max for just $13.79/100, and the 80gr A-Max for $14.92/100. Sweet deal.

Heavy Bullets for Competition
The 77gr and 80gr Sierra MatchKing are probably the “default” 22-Cal bullet choices among long-range Highpower shooters today, but we have heard many good reports about the 80gr A-Max and the 75gr and 80gr Berger Match VLDs. If you’re shooting an 8-twist barrel at long range, you should try all the options and see what shoots best in your barrel. The new 90-grainers from Sierra and Berger caused a stir when introduced in 2006, but we haven’t heard many reports from shooters using them in competition, possibly because one needs a very fast twist barrel (1:6.5″ is preferred), and the 80s already shoot so well.

Commercial .22-250 Remington Loaded Ammunition

There is a vast array of new factory-loaded .22-250 ammo available, with bullets ranging from 35gr up to 70gr. Good factory-loaded .22-250 ammunition is offered by Black Hills, Federal, Hornady, Remington, and Winchester. Most factory ammo features 50gr to 60gr projectiles. In this bullet weight range, the new Hornady Superformance .22-250 Varmint ammo is the king of speed. Hornady claims 4000 fps for its SuperFormance ammo, loaded with 50gr V-Max Bullets. That’s about 200 fps faster than other brands’ offerings with the same bullet weight range. See video below:

[youtube width=”600″ height=”350″]http://www.youtube.com/watch?v=7qYmxRIQJ5E[/youtube]

Black Hills 22-250Ultra-high-velocity .22-250 ammo loaded with very light bullets is becoming more popular. Black Hills sells .22-250 ammo loaded with 36gr Barnes Varmint Grenades. With a predicted velocity of 4250 fps, these will deliver serious “Red Mist” effect. Winchester offers a high-velocity (4350 fps) round loaded with 35gr lead-free Ballistic Silvertips. Remington UMC Ammo hits the 4000 fps mark with its UMC ammo loaded with 45gr JHPs.

If you are looking for bargain .22-250 ammo, consider the Prvi Partisan. Available for about $13.00 per 20rd box, this ammo has proven reliable and surprisingly accurate. It is widely available in a 55gr softpoint loading, rated at 3674 fps. One Prvi .22-250 ammo shooter notes: “[This is] almost the cheapest ammo available and still good quality. As for accuracy, I was able to shoot sub-MOA groups with this ammunition. The quality of the brass for reloading is fantastic (better than Remington or Winchester as long as you weigh them into lots). I have reloaded this brass 5 times and so far have not had any issues with brass fatigue, cracking, or brittleness. The only thing you need to keep your eye on is the primer pockets, they seem to be a bit deeper than other brands.”

Recommended .22-250 Rem Dies and Reloading Gear

Since the .22-250 is such a popular cartridge, all the major die-makers offer reloading dies. It’s hard to go wrong with a Redding Type ‘S’ Full-length bushing die — item 77106 for the standard .22-250 and item 77406 for .22-250 Rem Imp 40°. This will both resize the case (and bump the shoulder) as necessary, and allow you to adjust neck tension with bushings. Alternatively, you can go with a body die (item 75106), and a separate neck bushing die (item 78106).

If you load primarily one brand of bullets, another slick set-up is to buy a Forster full-length .22-250 sizing die (item 005221), and then send it off to Forster to have the neck honed for your desired amount of tension. Forster charges just $10 plus shipping for this service. This elegant one-pass sizing solution produces very straight rounds with low run-out. We also believe that doughnuts (in the neck) form less readily if you full-length size with non-bushing dies as opposed to using bushings. Bushing dies leave a little bit of the neck unsized, and that’s where the brass can build up.

For bullet seating, both the Redding Competition Seater (item 55106) and the Forster Ultra-Seater (item U00031) work great for the standard .22-250 case. If you shoot a .22-250 40° AI, Redding’s .22-250 AI Comp Seater (item 55907) costs quite a bit more than the standard version and Forster doesn’t list a .22-250 AI seater in its catalog. However, you can just run your chambering reamer into the inner sleeve of either die to fit the Improved case.

If you want the “Cadillac” of production seater dies for the .22-250, order the Wilson stainless seater with micrometer top (Sinclair Item 22250STAINLES) from Sinclair International. Costing only a few dollars more than a Redding Comp seater, this die is a joy to use, providing very positive control over bullet seating depth. When used with a quality arbor press, the Wilson offers unrivaled “feel” for bullet-seating force. This can help you monitor neck tension, one of the most critical factors in maintaining low ES and SD for long-range accuracy.

WARNING: With all loads, ALWAYS START 10% LOW and work up incrementally.
WARNING: ALWAYS start 10% below these loads and work up. Pressures can vary dramatically from one barrel to another. Seating depths have a huge effect on case pressures–moving the bullet just .015″ one way or another can push a “safe” load into the danger zone. Powder lot variances can be extreme–you may have to adjust a full grain or more. Whenever you buy new powder, even the same brand, start 10% low. NEVER assume pressures will be safe if you change lots or ANY component. Case web growth is probably the most reliable indicator of over-charge. By the time you’re getting stiff bolt lift or ejector marks with fresh brass you’ve exceeded proper pressure levels. Ambient temperatures can alter pressures considerably. Don’t assume cold weather loads are safe in summer. As you approach max loads, reduce the load increments. Just 0.2 grains can make a difference.

Great Factory Rifles in .22-250 Remington

A proper varmint rifle with a fat fore-end and stainless action and 26″ barrel, the Savage 12 VLP DM is ready-to-run right out of the box. With a strong, pillar-bedded laminated stock, and fluted 26″ heavy barrel, the 12 VLP DM can often deliver 1/2-MOA groups with tuned handloads and can easily shoot under 1 MOA with factory ammo. This model offers the flexibility of Savage’s new Detachable Box Magazine (DBM) — you can make quick follow-on shots, or easily switch mags to change ammo types. For 2010, you can get either a 1:9″ twist or 1:12″ twist barrel in your .22-250 model 12 VLP DM. We recommend the 9-twist version as it lets you shoot heaver bullets at longer ranges. The AccuTrigger can be adjusted down to about 1.5 pounds, so all you really need is to skim-bed the action and add a scope and you’re ready for the varmint fields. MSRP for the 10-pound VLP DM is $1041, with street price around $900. Both Right- and Left-hand versions are offered. If you don’t need the DBM, and prefer a 12-twist barrel, consider the single-shot model 12 BVSS which retails for about $120.00 less.

The Model 700™ VL SS Thumbhole (item 27447) in .22-250 represents one of the better values in the current Remington line-up. The VLS offers a stainless action with 26″ heavy ss barrel (1:14″ twist) with target crown. The laminated thumbhole stock has a roll-over comb, and a wide beavertail fore-end for stability in front bags. The thumbhole grip is nicely designed and comfortable in the hand. This is an easy gun to steer in the bags. Suggested retail for the Rem 700 VL SS Thumbhole is $1085.00. Street price varies widely — we’ve seen these advertised from $820 to $950.00.

The Howa m1500 Ranchland Compactin .22-250 is an excellent rifle for the price (MSRP is $550.00). This handy walk-around varminter has a blued action and 20″ barrel and weighs just 7.15 pounds. The m1500 Ranchland compact features a Hogue “over-molded” stock (with pillars and textured grip areas) in either black or OD green colors. As shown in the photo above, the Howa Ranchland Combo Package is also offered in Sand or Camo finish. The Ranchland Combo comes with a one-piece scope rail and a color-matched, Nikko Stirling 3-10×42 Nighteater™ riflescope and rings. These scopes and rings are anodized to match the color of the stock of the rifle. MSRP on the Ranchland combo is just $625.00. This short “truck gun” fits easily behind the seat of a pickup truck, or in an ATV rack. The action is strong and smooth, and the barrels are probably a bit better, on average, than you’ll get from Remington.

22-6.5×47 vs. .22-250 Standard and .22-250 Improved

In our Shooters’ Forum, there has been an interesting discussion of the 6.5×47 Lapua case necked down to .22 caliber. Forum members discuss the pros and cons of a “22×47 Lapua” wildcat versus the classic .22-250 or a .22-250 AI.

Forum member SkeetLee asked: “I am considering a .22-6.5×47 Lapua or a .22-250 AI. I like the Lapua brass and I have heard some good accuracy reports from the x47 Lapua case whether it be a 6mm or 6.5mm or even 22 cal. I don’t know too much about the .22-250 AI except that it’s pretty popular and it’s fast…. I don’t see much offered for reloading dies for the .22-6.5×47 Lapua. I know I can use a bushing die to neck size but what about full length sizing and seating dies? Does it make better sense to just go with the .22-250 AI?”

22-250 Ackley Improved

Respected Savage Gunsmith Fred Moreo, posting as “Medicineman”, offered this advice: “Why not get the best of both worlds? I built a .22-6.5×47 Improved for my coyote gun. It is easy as just running the .22-250 AI reamer in .050” short, and trimming the same amount off the dies. It is actually a little more efficient than the .22-250 AI. My best load for coyotes is a 65gr Sierra GameKing pushed by 39.4 grains of H4350 for 3750 fps. The Lapua brass will take more pressure than any .22-250 brass available [other than Lapua’s own], and last four times as long. The 65 Sierra GKs hit like a sledge-hammer, and were originally designed for shooting red kangaroos — they’re pretty tough from what I hear.”

22-250 Ackley ImprovedForum member Vic C. from Oklahoma has experience with the .22-250 AI, and has recently built a .22-6.5×47 Lapua. Comparing the .22-250 AI with the .22-6.5x47L, Vic tells us: “Accuracy should be very good from either caliber in custom barrels.” Vic continues: “I have two .22-250 AI barrels and a new .22-6.5X47 Lapua barrel that I’ve just started load-testing. The 22X47 Lapua case capacity is slightly more than a standard .22-250 Rem and less than the .22-250 AI (fire-formed). The advantage of the .22-6.5X47, of course, is the availability of Lapua brass. [Editor’s note: Now Lapua makes .22-250 brass so no case-forming is required]. I have Remington, Winchester and Federal brass for the .22-250 AIs and prefer Remington which I’ve found to be quite good, but not up to Lapua standards of course. Recently I’ve been shooting some reformed Norma 6XC brass in the .22-250 AI and find it to be of excellent quality. Dies for the .22-250 AI are much easier to come by than for the .22-6.5X47 Lapua. For a coyote rifle, if you’re not saving the hides, I think either caliber would be a great choice. For a PD rifle I would go with the .22-250 AI because of much less work prepping the hundreds of cases needed.

Comment by Ian Hames:

“I have personally had a love-hate realtionship with the 6-6.5×47, finding it painfully inconsistent from one day to the next. and would have to be really pushed into the idea of doing another, especially in a smaller caliber, however, the new .22-250 lapua brass is very easy to make into *X47 Lapua brass. The clear reason for doing a .22-6.5×47 over a .22-250 AI was the lack of .22-250 brass from Lapua. Now that is no longer a problem. Although I did experiment with 6XC Norma brass in a 6-6.5X47 Lapua in order to see if the flash hole was a factor, the results were no different than Lapua brass, so I do not ascribe to the notion that the small flash hole/prmer is a deficit in the 6.5×47 Lapua brass.

I’m all for doing something new and funky, but I would do a .22-250 AI in a heartbeat. Dies are there, the brass is now there, and the load info is all there too. I suspect this has the potential to be a killer long range cartridge with the 90 Bergers.”
