I had been having issues with my EDGE. i started off with Remington brass, H1000 and 300 Hybrids and LOVED EVERYTHING about life. 91 gr got me good accuracy @ 2840. But, after 6 - 7 firings the primer pockets started going away, so out came the Bertrom brass. Nothing but trouble. PSI signs right from the start with both H1000 and RL33. I scrapped the whole thing two or three times, but it got to the point where I had to do something, as there is no 300 Ultra brass on the planet!! So, I loaded up 50 rounds at 85 gr H1000 @ 2720 FPS. Shot bad, but I needed to get them all fire formed to see if i could get rid of the PSI. Anyway, I loaded my FFed brass from 97 to 104 of RL33....groups @ 100 to start. Put 3 in one hole @100 gr, so I loaded up 12 more and ran 3 over the M3......2960 FPS with 6 ES. 3 tiny (3 shot)groups again at 100. Happy, happy. The pic is of the backer as the paper target was damp and shredded on me. Now Ill fine tune at my 750 yard berm and be GTG...I HOPE!!
