[QUOTE="lancetkenyon, post: 2598283, member: 68875"] I have a few concerns with your post. Sierra doesn't make a 156gr bullet. They do make a 150gr Sierra Match King though. Amazing bullet. I have run them in a 1:7.5" 6.5SS at 3120fps out past 1500 yards easily. They actually suggest a 1:7.5" or faster on the box (used to say 1:7" or faster on the box), so I am not sure if you were actually "overspinning" them. A 6.5PRC will not outrun a .264WM when both are loaded to their max with all else created equal. PRC will be around 59-61gr +/- max powder charge. .264WM will be around 66-68gr max powder charge. In the engine world, there is a saying. There is no replacement for displacement. Same pertains to case capacity. There is NO WAY you are getting 50-60gr of any powder in the 6.5 Creedmoor case.
