Small rifle primers---there is no substitute

[moosemoose]

I built a rifle a couple of months ago and in the course of working up a load for it I have just about gone through my supply of small rifle primers. It seems that these little primers are very popular right now because they are hard to locate.

I was curious to know if there was a substitute and began looking for information. I ran across this article in varmint hunter magazine and thought I would share it.

I would be interested in finding out how CCI m41 primers compare with either the CCI 450, or BR4.

The M41 is a thick cup primer, if you can find them, buy all the guy has!

I have been using Wolf primers and they seem to work really well. Powder Valley has all you could want.

The M41 primers have a thicker cup and less prone to piercing from what I have read but how do they shoot compared to the CCI 400 / 450 or Remington 7 1/2? any experiences?

In my experience the wolf s show pressure sooner than others

It has been my understanding that CCI41 and CCi450 share the exact same cup and primer charge the difference is the anvil reducing primer sensitivity.

some of that info on that web page is wrong and has changed. The main thing is the CCI SP mag primes are the same as the SR primers. That is no longer the case. The SPM primers have changed the primer compound and is no longer the same as the SR primer. And the CCI SR primers are not supposed to be used in anything other than 22 hornet pressure loads in other cartridges that use the SR primer. Mags or 41 are what is supposed to be used in anything that makes pressure over 45K psi

The Tula SRPM's stand up better than Fed or CCI's or Rem. in my 6PPC and other high psi loads I use.

Please somone tell me I wasn't the only one who saw the post saying powder valley had wolf primers and shot over there

I read that and my heart went into defibrillation!! Then Mr. Common Sense spoke up and I looked at the date of the post.

……..??? These always amaze me.

No need in even mentioning the Wolf and Tula primers since they aren't available an haven't been for many years!

GREAT LINK!
Just one more reason to wander here. Collectively, probably several thousand years of knowledge and experience stuffed into the minds of the members of one really great site.

Most of the info in that thread is wrong. But people keep re posting it

I think it's because of the mild nature of the WOLF/Tula primer. I've been doing a head to head with WOLF SRM and CCI #41s over the last 3 weeks in .223 loads. CCI's goosed my velocities with 69gr OTMs 80 FPS on the same charge of H322.

I've been shooting Wolf SO LONG that messing with hot American primers completely derails my .223/5.56mm ammo approach.

That’s digging pretty hard for information when you go back in the archives 14 years!…. Still good info I guess

The main problem as I see it is that there are too many types of small rifle primers particularly in the CCI line...small rifle, small rifle magnum and CCI41 (magnums with a thicker cup.) It makes trying to keep things simple a bit harder. I use Winchester if I can find them.

I'd be happy using Winchester across the board. They're kind of the happy medium.
