Re: When to use Magnum primers?
I have several competition rifles and have selected the primers with best accuracy, i.e. in the 6mmPPC, I use standard Federal 205; .223, its the CCI BR 4; 6mmBR, magnums seem better, so I use the CCI 450 or Wolf small rifle magnum. Also, 30BR, I use CCI BR4. In hunting rifles, I mostly use standard primers, but for cold weather hunts, I found the magnums ignite a little better. You have to test and compare primers.
