I don't know but I've been told...that barrels are burnt out by excessive burning powder forced down behind the bullet at supersonic velocity. In rifles, that's easy to accomplish with 4000fps bullets and super mega magnums. In pistols, well, there just isn't enough room to fit the powder needed to torch the barrels quickly. Possible exceptions might by your 460XVR and 500SW high pressure, high capacity rounds, but typical service calibers are very far down on the charts as far as burning bores. Especially if you shoot unjacketed projectiles and don't clean needlessly, the bores will last pretty much forever (unlike slides, springs, and firing pins

)
