Large rifle primer vs small rifle primers - 6mm

[hibernation]

I have brass in both, and I have always ran SRP Magnums because I could find them easily as compared to LRP and never had a problem with them going bang until recently when I tried Staball powder and started getting some delayed fires. I switched to the LRP brass with the same powder and did not get any delayed fires, so I am staying with the LRPs until they become impossible to get.

How noticeable is the delayed fire? I've never actually seen it happen.

Berger factory 6 creedmoor SRP ammo - could feel and hear the firing pin fall completely before ignition.

Why? What’s so difficult about it?

People were wildcating SRP 308 Palma brass to get SRP pockets so might as well give the people what they want.

I can think of 5 calibers that I reload that have both. I buy large, random lots of brass, mostly for plinking/practice, so I have to sort every damned case for small/large and prime them separately. It's a &^%$#@ PITA as far as I'm concerned and adds another layer/time to the reloading process.

Serious question to add to the above question. What about small rifle magnum primers for a use case in cold environment?

Winter in NC Mn can be real cold and if you want to be certain your loads will fire use a mag primer.
When I was a kid my friend went into the cedar swamp for deer when it was -40° and he was using hand loads given to him so no idea what the powder primer situation was but the bullets barely came out of the 30-30 with deer in sight. He was not a happy camper to say the least.

The person who thought it was a good idea to make a cartridge with both sized primers should be neutered.

At one point, I bought some SRP brass for my 6.5CM because I could not find new LRP's.

I liked having a Plan B available to me.
