I picked up a 3 barrel Savage a while back just for the 6-284 barrel, had no idea what I was getting into. The 6-284 barrel was short chambered so I bought a reamer and finished chambering it. I found out that it had also been rechambered from a 6 BR chamber. The fireing pin spring was loose, so I had to work on the bolt. I haven`t got to play with it much and only with AA Mag Pro powder and CCI BR-2 primers, but can live with what I`ve got if I can`t get it better. I have a 5-shot group at 100 yrds. at .688 and a 3-shot at .460. The problem is that I shot the 5-shot group with the bullets jamed into the rifleings hard enough to pull the bullets if I tried to unload the gun. The 3-shot group was only jamed into the rifleings about .010 so I can unload them. I`m going to back them off another .005 and try that. I did try backing them up to abt .002 off the rifleings and the group size really increased. The best thing about it is that I shooting 105 gr Bergers with a 532 BC. at around 3,000 fps, guess as I haven`t cronoed them yet. Anyone have data on this round to share???
