Cool on the x-dies; I was wondering if they were good or not.I have been using the RCBS FL, X dyes for about 4 years with 3 different AR rifles. Never trimmed, no failures to feed. I was skeptical about the x dye which maintains the OAL of the case each time the case is sized. It works. I get over 10+ reloads per Lapua case. Just need to follow the instructions on the initial set up od the dye.
