Wolf small magnum primers

I've recently had several misfires with Wolf small rifle magnum primers in a 6mm BR with Lapua brass. The first time it happened was several months ago and I posted for any recommendations. I made certain that the primers were firmly seated until they bottomed out, etc. The same problem just reocurred the other day at the range. I've never had a misfire with CCI 450s and went with Wolf because of the price, availibility and reputation. The firing pin spring is an extra power spring. What gives?

My buddy just had 2 in a row- same scenario.
Maybe the primer pockets on the recent lots of 6 mm Lapua brass may be a tad deep?
My K&M primer pocket uniformer never touches the bottom.
 
I too have had misfires with Wolf LR primers. In reloading for a Swiss K31. I hardly ever shoot anything with LR primers but have started participating in military bolt action only matches. Narmally I only shoot SRP in ppc and BR cases. All I could get at the time was Wolf. Not impressed with the number of misfires. They were seated in cleaned pockets in Privi Part. brass. Only reloadable brass I could find for the 7.5 x 55. They don't seem to be seated too low and the Swiss GP 11 ammo all goes bang first strike, as does the Privi Part. Too bad the GP 11 ammo is berdan primed.

I tried them for WSM cases in large primer, hunting rounds. Immediate misfire......

switched to WLRM

I had two rifles with FTF using the Wolf small rifle magnums. One, a BAT action in .30 BR, Lapua cases. Shot a score match, 9 FTFs. Some said it was the BAT, or the Lapua cases.

OK, the other rifle is a Factory Savage 112 in .223. Winchester brass. Cases fired multiple times & neck sized only, so they fit the chamber. Another score match, 2 FTFs.

With both, the primer pocket unified with an old White ??? (Dick Wright's tool) . I use it to clean the primer pockets after each firing, so the pockets er pretty good. Primers seated firmly with a K&M.

This performance by the Wolf primers is not acceptable..
 
The primer cup depth on my Wolf SRM's (Lot 7-09) measure .111-.112", my Rem 7 1/2's, .116", F205's, .119". I've had enough misfires with the Wolf's (BAT, Stolle) that I would never consider using them in a match.

I must have gotten an exceptional batch, out of the 3,000 plus that I have shot I had one that failed to fire. When I pulled the bullet the powder had a lot of oil on it as did the primer when I punched it out. This brass was being fired for the first time after neck turning, I will continue to shoot Wolf primers = price = availability.

I will say this, the construction of the Wolf primers is not as robust as 205Ms. When I took apart the FTF rounds and punched out the primers, most times the anvil came out as a separate piece. Of course, that could have, probably did, happen when the primer was pressed out. I've also taken down & removed the primers of a number of cases using Federal and Winchester primers, and never see this.

I have no idea if this is a factor. If the anvil is in place and rigid, I'd think that's all that matters, not its performance when the primer is removed. On the other hand, if it is not rigid when struck (twice), I'd imagine that would be a bad thing. Perhaps I'm/we're using too much crush when seating them? One thing to bottom out the cup & maybe another to disturb the anvil?

Pure speculation.

Omigosh: another Francis. And this one seems to be as well informed and versed as I.

Oh my God 2 for the price of one.:eek:

Hmm. I'll add that when I decapped those that did fire, there were a number that came out in two pieces as well. Done using the Wilson decapping pin & base in an arbor press -- and the FTF's carefully. -- DISCLAIMER: I don't recommend this for live primers. It may be dangerous.
 
Excellent but unique...........

These Small Rifle Magnum from Wolf (Tul) are certianly unique.........

Can be frustrating... Can be a bit eye opening..Good and bad.

Short protrusion / small diam firing pins can cause occasional FTF... This with a not so firm slight crush seating = certian FTF's............

What I have found is that the SRM primer cake is "mild" ........ I shoot a lotta 22 and 6mm BR and along with several single base powders, I perfer a specific med to slow Ball powder that is known to be a tad hard to ignite.
With the Wolfs I get a clickkBang almost every time with Rem and Savage actions...Fed, CCI, Rem, Win >>>Standard<<< rifle primers DO NOT do this slight hang fire....

Now the positives I have found with the Wolf SRM...
In my PPC's, definate ES reduction over my "go-to" primers (Fed 205 / 205M)...
Load tunes seem to get very steady... Easier and a bit wider tune range... Found a few barrels that were deemed just "good", to "wake-up" with these Wolf's............:)
Set my personal best Aggs at 100 & 200 with Wolfs recently.

Think the mild priming cake is good in a ppc with our typical fast/med burn rate powders and effeciency of the ppc case......

So for myself... I use a domestic primer for my fun/varmint cartriges.
Wolf SRM in the 3 Benchrest actions I have NEVER had a FTF (even while fire forming)... The 4th BR gun that has an occasional FTF...Well, I'll save the Fed 205's for it....

Now with the better availability of domestically produced primers... This is kinda a moot point... Well till the primers become scarce ......Again.

Still, with all the issues, one should give these primers a try in there ppc whom have not yet... Can be eye opening.......;).Hopefully in a positive way..;):D

I have shot over 5000 of the Wolf SRM's (loaded on Dillon equipment) in AR-15 type systems with 1 failure to fire, thats not an extremely high rate of failure IMHO...I have tried them in my 6PPC (Stolle Grizzly II) in 50 rounds as a test and they seemed just fine with no FTF's. I believe that there have been good lots and questionable lots of the Wolf primers, maybe made in different facilities, that can present ptoblems. Supposedly...these are the same primers that are loaded into the Wolf brand 223/5.56 ammo and from what I can tell, there aren't many FTF's with those, although I don't use them myself!
 
I have not had any problem with the standard Wolf primers but was told (by someone who has shot a lot of Wolf primers) that the magnum version's primer cup is made of a different metal. It is harder and apparently can lead to inconsistent ignition and possibly misfires.
 
It is my feeling that The FffbrRrAnscissesss have answered to my sit'chyayshun........ I seated the primers using my handy-dandy Olde Schoole Hornady-by-Cabela's discontinued-for-liability-reasons handprimerseater.... It seats them only .001 below the casehead.


not enough evidentally

I use that marvel of invention the RCBS press and priming attachments for seating the wolf primers. I can't get them seated deap enough with my old trusty rusty blow up in your hand Lee primer seater as the Wolf is just a tad bigger in diameter. I like to seat them at .008-.010", that can be accomplished w/the RCBS if you keep everything tight. I got this setup about 40 years ago in a starter reloading kit from RCBS. Primers are easy to seat and depth consistant.

I haven't had a problem with the Wolf primers. But, I have only shot a tray of them. With the Lee hand tool. Similar seating to 205M.
Seem pretty good. Waiting to run out of Win. SR.
Wolf LP work great in my G21SF and 1911. :)

My primer pocket uniformer touches the bottom of any of my 6mm BR Lapua brass (250 rds.). I've never had a problem with any other primer. I use the Wolf .223 primers in my ARs, Mini-14 & H K and they function flawlessly.

What I'm posting is things that can happen to make a primer miss-fire and not saying that wolf is not miss-firing when everything is done properly.
When you fire form a case you want to seat the bullet into lands to eliminate any head space that is there. If you do not do this there may be enough head space that the firing pin is not reaching the primer as it should. It will also can cause inconsistent case blow-out and uniformity.
You want to also make sure that the cases are cleaned out properly to eliminate oil that was used when neck turning, etc. (This was previously mentioned)
Another reason would be that the case is over-sized (this is after having fire formed) creating head space (some may miss-fire and some may not).
