[QUOTE="SavageLapua, post: 826885, member: 69394"] I also run a 6.5x55 in a factory Tikka Varmint. My load is 47.5gr RL22, Lapua Brass, CCI250 Primers, and 140gr SMK average 2703. The ES (62) and SD (17) are higher than I'd like to see, but it shoots very well at 0.45 MOA. I've been able to narrow those numbers significantly by switching primers and trying different powders. I tested loads that would keep me in the same velocity node(~2750fps). 10 shot string Results: H1000, Lapua brass, CCI250, 140gr SMK, 3.100 COAL. ES=65, SD=17 Ave=2753 H4350, Lapua brass, CCI250, 140gr SMK, 3.100 COAL. ES=22, SD=7 Ave=2730 RL22, Lapua brass, FGM210, 140gr SMK, 3.100 COAL. ES=30, SD=8 Ave=2749 RL22, Lapua brass, FGM215M, 140gr SMK, 3.100 COAL. ES=32, SD=9 Ave=2789 10 shot groups at 100yards, non printed worse than 0.5 MOA. I'm planning on doing some more testing in the future with these particular powders and primers. Either way, I'm very impressed with this rifle and caliber. SL [/QUOTE]
