[QUOTE="MagnumManiac, post: 1483924, member: 10755"] Yes, I have a pressure trace and switching between a standard primer and magnum primer, even in a case as small as a 222 Rem, or as large as a 22-250, is enough to raise pressure by 8-10,000psi. So, you may be running right at max with your 45.8gr load, or well above it. Pierced primers are NOT always caused by excessive pressure, BUT in your case, I think a reduction in charge weight is in order. Just FYI, a small rifle primer handles far more pressure than a large rifle primer. Both the cup and pocket have far less area, meaning it takes more pressure to obturate them past their elastic limit. Cheers. :) [/QUOTE]
