We are often asked “Can I get more velocity by switching primer types?” The answer is “maybe”. The important thing to know is that changing primer types can alter your load’s performance in many ways — velocity average, velocity variance (ES/SD), accuracy, and pressure. Because there are so many variables involved you can’t really predict whether one primer type is going to be better or worse than another. This will depend on your cartridge, your powder, your barrel, and even the mechanics of your firing pin system.
Interestingly, however, a shooter on another forum did a test with his .308 Win semi-auto. Using Hodgdon Varget powder and Sierra 155gr Palma MatchKing (item 2156) bullets, he found that Wolf Large Rifle primers gave slightly higher velocities than did CCI-BR2s. Interestingly, the amount of extra speed (provided by the Wolfs) increased as charge weight went up, though the middle value had the largest speed variance. The shooter observed: “The Wolf primers seemed to be obviously hotter and they had about the same or possibly better ES average.” See table:
| Varget .308 load |
45.5 grains |
46.0 grains |
46.5 grains |
| CCI BR2 Primers |
2751 fps |
2761 fps |
2783 fps |
| Wolf LR Primers |
2757 fps |
2780 fps |
2798 fps |
| Speed Delta |
6 fps |
19 fps |
15 fps |
You can’t extrapolate too much from the table above. This describes just one gun, one powder, and one bullet. Your Mileage May Vary (YMMV) as they say. However, this illustration does show that by substituting one component you may see significant changes. Provided it can be repeated in multiple chrono runs, an increase of 19 fps (with the 46.0 grain powder load) is meaningful. An extra 20 fps or so may yield a more optimal accuracy node or “sweet spot” that produces better groups. (Though faster is certainly NOT always better for accuracy — you have to test to find out.)
WARNING: When switching primers, you should exercise caution. More speed may be attractive, but you have to consider that the “speedier” primer choice may also produce more pressure. Therefore, you must carefully monitor pressure signs whenever changing ANY component in a load. Glen Zediker recommends decreasing your load ONE FULL GRAIN when changing to a different primer type, one that you haven’t used before.

It may seem obvious, but you need to be careful when changing primer types for a pet load. Testing with a .308 Win rifle and Varget powder has confirmed that a primer change alone can result in noteworthy changes in muzzle velocity. To get more MV, you’ll need a more energy at some point in the process — and that potentially means more pressure. So exercise caution when changing primer types

Need Primers? Wideners.com has received a large shipment of Wolf Primers. Made in Russia, Wolf primers have worked well for many shooters. In many cartridge types Wolf primers have shown very good accuracy, and competitively low ES and SD. You should read our Shooters’ Forum threads about Wolf Primers to see if they would be a good option for you. We have generally heard positive feedback, with a few comments that Wolf primers may require a little more force to be seated properly, when compared to domestic-made primers. Current inventories are shown below.
Wolf Primers at Wideners.com (All In Stock as of 10/17/2013 at 10:00 am ET)
Prices do NOT include shipping and HazMat fees. Wideners says that up to 50,000 primers primers (That’s 10, 5000-count boxes) can go with one hazmat tag.
NOTE: Some shooters prefer the Wolf Small Rifle Magnum primers over the standard Wolf Small Rifle Primers because the cups are harder on the SR Magnum versions. Wideners does NOT currently have the Wolf Small Rifle Magnum primers in stock.

LuckyGunner.com, a leading online ammo vendor, has conducted a remarkable “torture-test” comparison of brass-cased and steel-cased .223 Rem ammunition. Four different kinds of ammo (one brass-cased, three steel-cased) were fired through four different Bushmaster AR15s — ten thousand (10,000) rounds PER GUN. The idea was to see if brass-cased ammo was better than the cheaper, steel-cased ammunition. During the course of the project, Luckygunner’s testers logged malfunctions and checked for accuracy, chamber pressure, gas port pressure, chamber wear, and overall barrel wear. At the end of the test, the well-worn barrels were sectioned to see the effect of thousands of rounds… and the results weren’t pretty.
Test Findings: For a multitude of reasons, the test crew determined that Federal brass-cased ammo was “healthier” than steel-cased ammo. The brass-cased ammo shot more accurately, had far fewer malufunctions, and produced less barrel wear. The USA-made brass-cased ammo also showed more consistent velocities. CLICK HERE to READ FULL TEST.
Watch the video below for a summary of results:
Torture Test Procedure
Four types of .223 Rem ammo were tested: Federal brass-cased 55gr FMJBT; Wolf steel-cased (polymer coating) 55gr FMJ; Tula steel-cased (polymer coating) 55gr Bi-Metal Jacket; Brown Bear steel-cased (lacquer coating) 55gr Bi-Metal Jacket. Each ammo type was paired with a specific Bushmaster AR-15. Tests were performed at various round-count stages:
- At the start: record accuracy, velocity, chamber and gas port pressures, make chamber cast
- After 2,000 rounds: record accuracy, velocity
- After 4,000 rounds: record accuracy, velocity
- After 5,000 rounds: record throat erosion, make chamber cast
- After 6,000 rounds: record accuracy, velocity
- After 8,000 rounds: record accuracy, velocity
- After 10,000 rounds: record accuracy, velocity, chamber and gas port pressures, throat erosion, extractor wear, chamber cast, barrel wear, make chamber cast.
During testing, rifles were cleaned according to a preset schedule and temperatures were monitored. After testing, LuckyGunner sectioned the barrels and made careful inspections.
Click the links below for specific data, test results, and conclusions:
During the testing process, all malfunctions of each rifle-ammo combination were logged. The brass-cased Federal ammo was the clear winner:
Federal: 10,000 rounds, 0 malfunctions.
Brown Bear: 10,000 rounds, 9 malfunctions
(5 stuck cases, 1 mag-related failure to feed, 3 failures to cycle.)
Wolf: 10,000 rounds, 15 malfunctions (stuck cases)
Tula: DNF (6,000 rounds in alternate carbine, 3 malfunctions) |
 Barrel Wear and Throat Erosion
Some of the barrels didn’t make it to 10,000 rounds: “The steel cased/bimetal jacketed ammunition caused accelerated wear to the inside of their respective bores. While the barrel of the Federal carbine had plenty of life left, even after 10,000 rounds … the Wolf and Brown Bear barrels … were completely shot out by 6,000 rounds. At the end of the test, the chrome lining of the Wolf and Brown Bear barrels was almost gone from the throat forward, and the barrels had effectively become smoothbores[.] A throat erosion gauge could be dropped into the bore from the muzzle end with absolutely no resistance.”

Wolf Match Target and Wolf Match Extra ammunition is justifiably popular with competitive 22 LR shooters. Wolf Match Target, at $4.90-$6.20 per box, shoots as well as many types of 22 LR ammo costing much more. (Price varies with quantity purchased.) We recently chronographed Wolf Match Extra ammo (using multiple chronographs), and it showed lower ES and SD than some lots of much more expensive Eley ammo. But Wolf rimfire ammo is often in short supply.
 SK Ammo — Made by the Folks Who Make Wolf
What to do? Here’s a tip — if you like Wolf Match, try the SK match ammo. SK Jagd Munitions actually manufactures Wolf Match ammo. The gold-box, SK-brand ammo is made in the same German plant as Wolf , and testing shows SK can deliver the same accuracy and reliability as Wolf. The SK Standard Plus is the equivalent of Wolf Match Target, while the SK Rifle Match is the equivalent of Wolf Match Extra. SK offers a wide range of rimfire match ammo at affordable prices. Here are current offerings at Champion Shooters Supply:
SK Rifle Match: $7.90 (50-rd box)
SK Pistol Match: $6.00 (50-rd box)
SK Standard Plus: $5.00 (50-rd box)
SK HiVelocity: $6.50 (50-rd box)
SK HiVelocity SPC: $6.50 (50-rd box)
SK Subsonic: $6.50 (50-rd box)
USER REVIEWS from MidwayUSA:
SK Rifle Match:
“I’ve tried over 20 different brands of match .22LR in my Anschutz 1907 including the various Wolf, RWS, Aquila, Lapua, and Eley loadings and the SK Match was one of the best. It was VERY consistent. 10 shot groups of 0.25″ to 0.3″ are the norm at 50 yards. Unlike most of the other less expensive ‘match’ ammo, the SK has yet to throw a bad flyer in 500 rounds. The Eley Tenex Ultimate EPS and Match EPS gave similar results. I consider the SK Match to be the best value for my rifle.” — D. Fletcher, TN
SK Standard Plus::
“I bought this because the Wolf MT is getting hard to find. This is the same ammo as the Wolf. I tried it in all my rifles and get about the same groups as the Wolf. Had no problems with this ammo and recommend it highly.” — H. Disharoon, VA
“Oh No — The secret’s out! For an exceptional price, this is absolutely the best .22 target ammo. I use it mainly in my Custom Ruger 10/22. CZ 452s just love this stuff. A majority of the silhouette shooters at my club use ‘SK Std Plus’ during matches and practice. I have shot cases of this stuff and can only count very few fliers.” — J. Batterton, AR

TulAmmo Primers Are Same as Wolf — But Cost Much Less
Powder Valley Inc. now offers Russian TulAmmo primers. TulAmmo primers (for rifle, pistol, and shotgun) are the exact same primers as Wolf. Both TulAmmo and Wolf primers are produced in the same Murom Apparatus Producing Plant in Russia and they have the same product codes. However, TulAmmo wholesales its primers at lower cost than Wolf-branded primers. Powder Valley is passing this great savings on to the customer. You will find that in many cases TulAmmo primers cost 15-20% less than the identical Wolf primers.
TulAmmo offers Non-corrosive Boxer primers, Lead-free non-corrosive Boxer primers, and Non-corrosive Berdan primers in all popular sizes including small rifle, small rifle military, small rifle magnum, large rifle, large rifle military, and large rifle magnum. There is even a special .50 BMG primer. Product codes are listed in the chart below. For more info, visit the TulAmmo USA website.
