Just for fun, I did a couple of repetitions putting 10 old beverage cans full of water on the berm and reducing all 10 to shredded scrap for recycling from 200 yards with 10 rounds loaded. Gratifying, but I need to concentrate improving my wind reading & mirage skills for (300 yards & up) accuracy. If I can only expect 2,500 round barrel life, make it count.

When I shoot my bolt gun, I am completely in tune with the rifle from the easy of the bolt sliding forward to how much pressure to close the bolt to the easy of extracting the spent case and also the barrel heat. Take 3-5 shots and then let her rest. My precision 6mm has a 1500 round count life...I am painfully aware of barrel life. Luckily it is slow measured shooting.
My observation is that for the typical shooter at the range none of these lessons / habits are maintain when an AR Platform is being used. No one thinks about barrel heat. The 10/22 / Potato Chip mindset takes over...the rifle is made to withstand 20-30 round magazine dumps...right!!! The only time anyone notices the barrel heat is when it gets so hot that their hands start getting a little burned while holding the handguard. At my range I have watched guys bring a new case/flat of ammo (1,000 rounds) and go through all of it in one session... at the 50 yard line shooting a paper plate that eventually is nothing but the outer 1" rim of the plate hanging by a clothes pin. Load 30 round magazines and squeeze trigger every second until empty and then load the next 30 rounder...2 hours late they are ankle deep in spent brass that they throw away. It is shocking how few AR15's get stretched to 100 yards, lone enough 300 yards or more. It is dumbfounding!!! I have seen plenty of guys just shoot their AR 10's at 50 yards as well...
During the design/day dreaming stage of my AR10 build, I decided that I wanted an accurate rifle but the overriding priority was that it be utilitarian and only chasing medium range plinking (800 yard max). Zombie apocalypse and all that... I settled on .308 for the barrel life and availability of reasonably priced ammo (ignoring reloading in the decision process).
