My advice is to find out if the problem is pressure, or primers. The way to do that is take your decapping rod out of your die, and see if you can push the primer out by using the palm of your hand. If you can push the primer out, the pocket has swelled. If you have to use the press to get it out, then see if you can seat the primer with your finger. What you are looking for is an expanded pocket that means the pressure is too high. If the pockets are still tight, then get some CCI41's, or some Remington 7 1/2's.
I have the same rifle. Never pierced a primer with it, but have opened a few primer pockets along the way testing different powders and bullets.
