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?
This is the classic problem which I have struggled with for some time. The 6.8 spc will work for mulies out to 300 yards, but it is light for the task. The 6.5 Grendel does a bit better job, but is still lacking power for the long shots. The 7.62 x 39 likewise will take deer out to 300 yards, but is anemic for elk.
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.
