It's my goal to 'shoot out' a barrel.
OK, not really, but you get my point.

I actually get excited when I shoot a barrel out on one of my bolt guns. I never buy the same brand of barrel twice, always like to try something else. Next barrel will be a Schneider, and maybe with polygonal rifling.
Another, and even more depressing, way to look at it is this. If you agree that the cost of a well done barrel replacement is around $800, that means we pay about $8000 per minute of bullet in barrel time. 
Yep, heat and friction are the culprits in all "wearing out" of things. Then let's look at drag cars..at 1/4 mile per run, not many miles on the motors before they are toast, i guess....Top Fuel, meh..
Depends, Hayabusa motor turning low. 9s -high 8s can last several seasons with TNT nights thrown is for good measure.
But yes putting maximum strain on anything will cause it to burn up quicker.
Yes, the motors vs projectiles probably wasn't the best comparison..Friction causes heat, so we oil and lube....hopefully.
I was just thinking the same thing about my Mosin when I read your post...
