[QUOTE="thor447, post: 3659700, member: 24867"] I got out to Lexington today with a friend of mine and did some chrono testing on this new 6.5CM load. Without posting tons of data, here's what took 1st prize today. 6.5CM - CCI LRP's, Lapua brass, H4350, 150gr Sierra Match King - all shots taken at 100 yards. [B]1. [/B] Not record setting numbers, but pretty decent. The 6 o'clock shot was the last one in the group, and I'm chalking that one up to shooter error. 2nd group listed below had the same thing! Description: 40.2 # FPS FT-LBS PF 4 2691 0.00 0.00 3 2680 0.00 0.00 2 2704 0.00 0.00 1 2682 0.00 0.00 SD: 10.9 FPS Min: 2680 FPS Max: 2704 FPS Spread: 24 FPS [ATTACH type="full" alt="1635032836182.png"]229954[/ATTACH] [B]2.[/B] The best SD and ES I've ever gotten before from a single string. The first three shots were all touching, and I was stupid enough to see it and get nervous on the last shot, which went low (and I'm betting was fully shooter error). Description: 40.4 # FPS FT-LBS PF 4 2706 0.00 0.00 3 2701 0.00 0.00 2 2701 0.00 0.00 1 2691 0.00 0.00 SD: 6.3 FPS Min: 2691 FPS Max: 2706 FPS Spread: 15 FPS Shot/sec: 0.1 True MV: 2700 FPS [ATTACH type="full" alt="1635033037030.png"]229956[/ATTACH] All of these shots were taken on new Lapua brass. Now that I have fireformed brass, I'll try to get out again soon, with some loaded up in this powder range & CBTO. I've very pleased with the consistency of the brass. I prepped 50 pieces of fire formed Lapua brass this past week. All shoulders set back .002, all lengths were identical, neck tensions set with the mandrel at .002 as well. Hopefully I can get good results with the fired brass. I may have to tweak it a little further, but I'm pleased thus far. If I can shoot better and eliminate some of the jitters when I have a good group going, I think my rounds are capable, but I'll take 6.3 SD's all day long!! [/QUOTE]
