6mm ARC

[biodsl]

BTF's signature line lays it out correctly. For a civilian shooter who hunts, I think the Grendel would have the edge. It's pretty impressive what this cartridge can do on hogs, deer, elk, moose, caribou, aoudad and the like. Remember, the Grendel was developed as a hunting round. It has a track record on game, something that will be while in coming for the 6 ARC.

However, open your favorite ballistics calculator and run the numbers on 6mm bullets at 2,700 fps. Run them at 2,600. Run them at 2,500. It's shocking to me. If your goal is an improved Designated Marksman's cartridge, you just found it. The Hornady 108 grain ELDM at 2,500fps is still supersonic at 1,000 yards at standard atmosphere. I'm pretty sure you can achieve that velocity out of a 14.5" barrel. Can you say RECCE? At 7,000 feet (think Afghanistan) it's supersonic at 1,200 yard. It's no wonder the military interested in a M4 platform that can perform to this level. The problem is going to be finding a scope that can exploit the cartridges capabilities from zero to 1,200 yards.

A 6.5 107 Sierra Matchking drifts almost 7 inches more than a 6mm 108 ELDM drifts in a 10 mile cross wind at 600 yards. That number grows to 2 feet at 1,000 yards.

I enjoy my Grendels very much, but there's no denying the increased range and hit probability of the 6 ARC.
