I tried that first and wound up pushing the neck down. frown

I have two m14's and a 141 and as a rule they nibble at the rims a bit when they extract the fired case . I clean the nibbles up with a small fine cut file but eventually they get rougher than I want to use. Mine are some of my favorite rifles.
The ammo looks to be 60's or 70's. Graf's was out last I checked (a couple of weeks back). I need to learn how to anneal. smile Thanks for all the help guys.
