Having reloaded and manufactured many custom rounds, I use different primers to prolong the life of primer pockets. I start by using the smallest diameter primer that fits snug in the pockets. As the pockets loosen up I switch to a larger diameter primer. As an example for large primers I use rem 9 1/2 to start with then switch to a larger diameter primer as the pockets loosen up. Their are many charts available on primer dimensions both large ans small.
