[QUOTE="backwoods83, post: 2217816, member: 29890"] More data collected today, for anyone who is interested. I'm still having a bolt unlocking issue that's driving me insane. The rifle has potential though, and the barrel is speeding up slightly. I also made the mistake of drawing 3/8" dots, forgetting that the scope has a half moa center dot, so I'm not making excuses, but the groups could be better. RL17 data Reformed Starline 6.5 Grendel brass, trimmed 1.489", CBTO 1.705", .010" jump, 2.280" OAL, 105 Berger vld target, CCI 450s 28.7grns 2603fps avg SD 4.3 29grns 2628fps avg SD 12.5 29.3grns 2675fps avg SD 8.3 29.6grns 2685fps avg SD 10.8 29.9grns 2721fps avg SD 7.6 30.2grns 2741fps avg SD 11.3 Node from 29.7 to 30.3 and a nice full case with minimal powder compression, absolutely no pressure signs. H4895 data. 26grns 2647fps avg SD 13.6 26.3grns 2672fps avg SD 10.2 26.6grns 2716fps avg SD 8.4 Node appears to be 26.5 to 26.8 grns, good "Stable" powder load with around 90-92% case fill.

Target is at 100 yrds and the groups follow the data sequence. [/QUOTE]
