Wasn't sure where to put this.
Im having a heck of a time with groups opening up with my .223. I thought it was my new bullets im trying. Magtech brand. The higher velocity the more the spread. So today i took out some loads with Berry's and Mag tech. Same deal. I did have ring clamps getting loose before. That is normal from use. Remedy to that was some clear nail polish. When i got home i went over the whole gun. Checked free float with a dollar bill it was fine. Checked action screws all snug. Then i decided to take the scope off and check the mounts them selves. Back mount. One screw was loose 1/4 turn. And the front one screw was loose a 1/2 turn. So i re-mounted them with blue loc-tite.
