Home Forums Reloading Big Game Rifles Unsual amount of cratering when using Fed 215M's(are they soft)?

I have had half a dozen or more 257's, custom and factory.

Cratered primers seem to be par for the course in this caliber, especially when you stomp on the gas.

I suspect that over size firning pin holes in the bolts are a culprit.

I never popped a primer in a 257 Weatherby, however it is prudent to always wear safety glasses when shooting.
