[QUOTE="rammac, post: 1944813, member: 27761"] I don't have Hammer bullets in my software so I used a 196gr bullet that probably doesn't have the same shank length which means that some of the data will be slightly different due to frictional forces being different. I've posted what I would consider the maximums, based on the estimated chamber pressure, for N570, N560, and Retumbo. N570 approx 89 grains for a chamber pressure of 64,000 PSI (compressed load) [ATTACH type="full"]204524[/ATTACH] N560 approx 79 grains for a chamber pressure of 64,000 PSI [ATTACH type="full"]204525[/ATTACH] Retumbo approx 87.8 grains for a chamber pressure of 64,000 PSI [ATTACH type="full"]204526[/ATTACH] Personally I like the looks of N560 the best. I'd start with about 73 grains of N560 and work my way up. N560 looks like you can get good accuracy along with low extreme spreads and standard deviations up around 78 or 79 grains although you might see slightly better precision (group size) at the low end, around 73 grains.
