I also never used a mag. primer in an 06 size case, in way below zero F weather, and i've never had any problems at all...

So what is the bottom line. Does the extra fire from a magnum primer hurt anything?

Can this be skirted in the pool of you can never have too much, gun etc...?

No, you can hurt performance and with the wrong powder and load, can actually drop velocity. If your shooting 4350 or faster in say a 300RUM or even a win mag with a light 150-165gr bullet, you can get away with a reglar large rifle. But loads with RL22 and slower, needs the extra fire.

I have tried 270win's and 308's with 215M primers. And both times good known loads (with 210's) now shot groups twice as large.

I have all of them but probably use the Nosler Manual the most. Sierra is a good one too. I know the Hornady manual by heart as it was the first one I ever owned.

I have lost count. I just bought Lyman 48th, and I am disappointed. I like the old Sierra format. I mostly use internet for modern calibers,too much lawyeritis in most of the new manuals, Tom.
