[QUOTE="Varmint Hunter, post: 2619402, member: 313"] Just for fun, I've been testing the 85gr Hammer bullets in a 26" Browning HC McMillan in 6.5 Creedmoor. I'm using Lapua SRP brass and CCI 450 primers and crimping with a Lee FCD. Varget seems to be the favored powder for this combo so that's where I started. All groups were shot at 200yds. As usual, I started with a moderate charge and worked up slowly. As I got closer to the top, I only increased charge weights by .2 of a grain. Standard deviations were (often) remarkably low. A previous test revealed a good node at 45.1 so I retested that charge weight first and then progressed upward. I expected to see pressure signs at about 3,500 ft/sec but that didn't happen. [B][U]200yds[/U][/B] 45.1 Varget - 3,542-12 = grp .77" 46.5 Varget - N/A = grp 2.00" 46.7 Varget - 3,662-3.2 = grp 2.95" 46.9 Varget - 3,672 - 5 = grp .94" Even at the highest charge weight, primers were not flat, no ejector swipe, bolt lift was normal and cases ejected smoothly. There is apparently still some room for growth. With groups under .5moa I'm going to test these again at 400yds and might try one last increment at 47.1gr. [/QUOTE]
