Wolf S/R & S/RM Conundrum..

[ShootDots]

i posted this last June, wasn't able to diagnose the problem. but did speak with a guy that has the same action as mine same result they would not reliable fire the wolf. when they would shoot they had better numbers for my load so i would like to find a solution.

Evening june 2015

I have the Tula SRM primers, with a bench mounted priming station with incremental adjustments. I have used the same system for years and the WLR, Federal, and Remington have had zero FTF. With the Tula primers i have just over 1% failure rate. I have adjusted the depth of the primer from flush to slight (visible) crush with similar results. i can not get 100% ignition from this lot of Tula primers.

F/TR Bolt action rifle: I thought it was the firing pin so i measure the protrusion at .0375. This number is low for a custom action so i order a new firing pin and the new length was .0475 with the new firing pin i expected 100% ignition... sorry again i had FTF but not with the Fed or Rem i am not sure if the cup is too hard or other factors. When breaking down the FTF loads i have only seen one primer with no anvil. i can provide the lot number put i bought these primers in 2012 so i am not sure if this is relevant to the ops issues.

If anyone has a solution i am open to suggestions i am sitting on thousands of these primers.

Trevor, I have read everything I can about the "Iffy" ignition of the S/R Wolf primers and I can't figure it out. I have also seen where the Large Rifle Primers are absolutely flawless and produce excellent results on the target too! The Small Rifle primers also have excellent results on target too! This phenomenon has been well discussed on this forum and at the firing range too! It is evident many, if not most shooters, have zero problems with them.. It is also just as evident that something is amiss with the S/R primers in more than a few rifles>>> My question is WHY would the Wolf S/R primers work in my 6mmBR, fired from my Rem (unbushed by the way) where I have problems with other actions / cartridges or primers??

Hi Ben,

Sometimes the question contains the answer. So, your primers work without fail in one rifle, but not so in another of a different make. Seems to me you should dig a little deeper on what is different on the action(s). I'd measure the following for starters.
Firing pin protrusion: .050-.060
Firing pin fall: .200+ .250 being ideal
Firing pin strength 24+ lbs
No firing pin interference of any sort.
Firing pin size: small=better ignition
We've used thousands of srm primers in 6.5x47 with zero failures. We've used 20-30k over the years in many cartridges including the larger 308win without a single ftf. Now maybe we got lucky and got the good stuff, but I doubt it. Check your ignition system carefully, including the trigger. The problems I've seen have never been traced to bad wolf primers.....always mechanical or reloading issues.

Wolf primers are hard and mild, which makes them "reveal" ignition problems more than other primers.

Thanks Scoot>>> I will visit my 'smith either this week or next to see what may or may not be going on.. I do want to get to the bottom of this! I have nearly 6K of both the SR's and SRM's so I want them to work for me! LOL! I am going to try an experiment Scott>> I am going to load some in my 6.5 x 47 and JAM the dog out of the bullets to REALLY hold the brass against the bolt face to see if that makes a difference.. It is worth a shot.. Thanks for the input and those dimensions>> I will bring it to Omar's attention so he can take some measurements..

if the old Rem has the original firing pin it may have to do with the weight of the pin itself instead of the springs,,I know when I was having a Rem bolt bushed my smith said to not get the light pin gre-tan offers but to have my factory pin turned down,,theory is that the heavier pin delivers more consistent ignition than a faster lighter pin,,

I have had a few misfires in my Stiller Tac 30 and its fluted pin with Tula primers,,I have had none problems in my 700 action with Rem factory bolt that was bushed by gre-tan and the factory "heavy" pin turned down to fit the small hole,,
