AR-15 using a simple blowback operation
I don't know squat about the following: I have read that blowback systems using relatively heavy loads (e.g., 45 ACP, 9mm) will shorten the life of either a lower, upper, or both.
True?

As for all of those, which would be the best for hunting mule deer and quite possibly elk? Any, which ones?
6.8SPC would be good for mule and could work for Elk as well.Quote:

Sadly, the only rounds there which I personally would consider adequate for elk are the 458 Socom and the 50 Beowulf, but those are not long range cartridges. A pretty good elk rig would be an AR10 in .338 Federal. A good longer range deer rig would be an AR10 in 6.5 creedmoor. But I prefer the smaller dimensions of the AR-15, so it puts me in a quandry.
