Are soft points ok in an AR? Do they cycle ok? Dirty the action up, or perhaps the barrel?
I suppose I could keep two different types of ammo, but that isn't something I want to do. I already have 16 different calibers/gauges
You could also take a look at the Colt 6721. They are available with the 1/9 twist rate if that is what you would prefer for the lighter bullets. I own one and it has been great for me so far. The difference between a 6721 and the 6920 is the slightly heavier HBAR barrel on the 6721. Since you mention this would mainly be used as a range gun, a few extra ounces isn't a huge deal.
