[QUOTE="omt223, post: 2297371, member: 36222"] I just got my Bergara back from cutting the barre (from 26 to 22") its a HMR that I changed the stock on (to a MC3 legend). [B]300 win mag[/B] It has a mark 4 on it, stock trigger. I have been getting 5 round groups that for the most part separate out into two acceptable groups but as a whole aren't. I have about 8lb of surplus Wc857 that I have been messing with as well as some RL25, and 4831. I am trying to work up loads with 180gr SSTs and 175 nosler CCs. I have some 220CCs but havent messed with them much. I think I am about ~0.02 jump but dont have my gauge (gave it to a friend since I am in school, and of course ended up needing it) I have been using CCI 200s; I do have some magnum primers but have been told they are largely unnecessary, maybe thats wrong. As far as the powders, I have tried from 77gr up to 79 of 857; ~78 seemed to be the most promising but nothing special, 79 really opened up. Largely the same with the other powders. I don't have the range for a proper ladder at my disposal within reasonable distance. Here are a few of the targets, I have more but they are for the most part the same.
