[QUOTE="Crowe284, post: 1404638, member: 97064"] Reporting back. So as mentioned, I started out with a .313 bushing. I bought a .312 and a .311 bushing to try. The .311 bushing, which is what the virgin brass measures, got me to .311 with a .281 inside neck diameter. I sized 3 pieces of once fired brass with a Redding neck sizer die and shot. The problem is gone and accuracy is even better with 4 of the 6 groups shot measuring .2 or less (one holers). I fired a total of 18 rounds and all of them were with the same 3 pieces of brass, so they now have 7 firings on them. The 7th firing was pretty tight to chamber but now I know three things. First, the neck tension solved the problem with powder on shoulder. Second, I can get at least 6 firings out of them before having to bump and third the Norma brass is good stuff. The primer pockets feel as tight as when I started with them as virgin brass. The load I’m using is not a light one as I am shooting 63.8 gr of H1k, 215 fgmm primer and 180 hybrid .025 off. I did measure my throat today before starting and I have had .006” of erosion in 180 rounds. I want to thank all of you that offered up suggestions to help me out with my problem. Very best to all, Dusty Crowe [/QUOTE]
