Energy kills. And a lot of guys say 6.5 Grendel with a thermal for night hunts is a good set up. And so Ive seen on TV
. Another says he going to a 450 BM. I have both in a AR's. So I ran the numbers through Applied Ballistics and heres what up. I guesstimated a 22 cm with a 70 gr tsx could get 3450 fps. That 22 cm has 1200 #'s of energy at 200 yards. A little more then the 450 bm and a little less then the 6.5 Grendel. But that smaller diameter bullet going faster with more energy has got to penetrate better then the 450 bm. Dont get me wrong, the 450 is great at close range but sheds energy fast.
I dont see why that 22 cm with a solid wouldnt work to 200 yards. Especially if its an AR platform. But you have a great reason to build yourself a nice 6.5 Grendel or 6 ARC AR. The 6 ARC is really just a 6mm Grendel and will outperform the 6.5 Grendel at long range. And theres probably no better round then a 6 or 6.5 Grendel for a kids/women's/recoil sensitive persons1st deer rifle.
