Well the 6.8 SPC develops 44% more energy than the .223/5.56 NATO. with that extra energy and a bullet that weighs twice what a .223/5.56 bullet weighs, I don't think it would make a good home-defense choice. I keep a .223 AR carbine (you've seen the pictures) near my bed, along with a pistol. But an AR is almost too much round for inside a house, particularly if you have loved ones in other rooms. Really, a shotgun would be a better choice, but I don't own one.SigOperator02 wrote:For a happy medium at the house I decided to go with either .223/5.56mm or the 6.8 SPC calibers for home.
If you want to get two uppers, one in .223 for CQB, and the other in 6.8 SPC for hunting, that would make some sense. That said, one of my good friends who has a large lease bags at least a couple of his deer every year with an AR15 in .223. His other hunting rifle is a custom built bolt gun in .264 Winchester Magnum which pushes a 140 grain BTSP at 3,200 fps.
