Oh, I've put a ton of ammo through it, usually whatever is cheapest. Just have never shot that much ammo at one time except when the military was paying for it with issued weapons.
More of a general statement for the masses.
So many gun owners just never "Run" their guns and when they do it is not run hard.
Folks saying they have never experienced an issue with the gun they shoot and when asked how they run them the round count is 50 to 150 total spread out over 3 or 4 range trips. No issues with this but that is not a test.
