I want to build an upper for my AR in a hunting level caliber. Use will be for deer and hogs, at less than 200 yards. In all reality most of my kills have been closer to 50 yards than 200, or even 100. Looking at it I have been primarily considering 6.5 Grendel, 450 bushmaster, and 458 socom. I like big slow moving bullets with good knock down power, so I’ve been leaning towards the 458, as I think it has some advantages over the 450. But it is so much more expensive to buy factory loads for, and in the end I think one or the other caliber will win out, and it’s looking like it will be 450 BM. The 6.5 doesn’t seem like a bad choice, but it seems more suited for longer ranges and the bullets are on the light side of what I would be comfortable with. But I’ve seen some deer killed with them and no problems.
Any body have any advice or things to consider? Or want to talk me into another caliber? I know people will say 300 blackout, but it just doesn’t impress me. Once I decide on a caliber I’ll have other questions but I need to pick one first.
