I recently picked up a 45 Raptor for hunting in Michigan, and would really like to stretch the legs on this bolt gun. Obviously, with a 250 grain low BC bullet, getting consistent velocity is going to be really key to long range accuracy. I have loaded a couple of other straight walled cartridges and have gotten them to group well at 100 yards, but have never really found the sweet spot for consistent velocity. For what it is worth, i don't have an issue with getting low ESs in my bottle neck cartridges, so I think that I'm missing something as it relates to straight-wall cartridges. Please advise if you know what is different, or what I might be missing. Thanks.
