loading for 204, in a rem 700 sps varmint with benchmark and 39gr sbk at low charge weights (20 gr) i was getting cratering without even the primer starting to flatten.
i disregarded it as a tolerance error around the firing pin and judged pressure off of primer flattening and velocity. i now have some really nice loads (25.3gr) that shoot awesome the primer isn't completely flattened but it's mostly flat. the bad news is that the primer still craters and flows back around the pin. i have shot lots of these and rolled a few coyotes with them too, i've never had a primer pierce or any other problems and the gun is very accurate.
should i fix it if it isn't broken?
