[QUOTE="KH_Outdoors, post: 2804308, member: 123559"] I just went through load development this week on my 7 saum with the 143 Hammer Hunter! Here's what I came up with. 22" 1:8 tw Benchmark Carbon Sendero Light 143 Hammer Hunter @ 2.985" COAL (.050" off) N560 ADG Fed 210M Found pressure at 65 Gr (heavy bolt lift). I ran a charge weight ladder for pressure from 60-65 in .5 gr increments. Then backed off and shot groups from 61.5-64 gr in .5 gr increments. 62 & 64 gr are the lower & upper accuracy nodes found. Both consist .5" or less 3 shot groups at 100 yards. 62 - 3030 fps 64 - 3100 fps Hope that helps! I imagine RL23 would do well. And also, switching to the Fed 210M's showed significantly lower ES/SD compared to CCI250's from my testing. Thanks [USER=116240]@Longtine88[/USER] for the tip on that one! [/QUOTE]
