How long does a barrel last?
I've been reading a few books on reloading and among the info in there is leading of barrels, getting your specific gun barrel 'slugged' so you know it's true caliber so you can buy / make bullets that fit properly (for accuracy as well as to avoid excessive pressures).
OK great, but often enough it's mentioned about 'wearing out' a barrel (specifically regarding high speed rifle rounds).
So if one shoots competitively with a pistol and puts 3 to 5,000 rounds through a barrel in a year will that have any appreciable 'wear' on the barrel? Affect accuracy? Will choosing a particular bullet or load make a difference?
