RE: Pressure Signs
I found that while I'm reloading for my 300 Win Mag, that Federal primers will flatten out quite a bit, but Win, CCI and Remington primers don't at all.
This is with 200 grain bullets and exactly mid point between minimum and maximum powder load of IMR-4350.
After telling this to a local gunsmith, he commented that he liked Federal primers because they were very "soft." He said that because he thinks they just "fit" better in the pocket because of the softness.
(edited to add this question) Has anybody else found this to be true? The softness?
