I know this post would be universal to about any caliber but I am going to specifically say 6br because that's what I load the most. The reasoning for the post is I have been waiting multiple videos of well known and very successful shooter from BSWN and their sizing techniques. First off I want to say I'm still relatively new in the shooting community and have been mentored into using a body die to bump the shoulders back and to neck size. So far the results have been fantastic (for me). But I was kind of shocked when I heard all of these interviews saying they only FL size, they never neck size. So my question is why may that be? And what have you all found success with. Also not for my example these cases only have 3 firings on them.
