Hi Guys,
Probably a silly question, but I am curious if anyone has any actual experience wearing out a rifle barrel shooting cast bullets.
To preemt a common misconception, yes, .22 lr barrels do wear out. In fact I have a shot-out .22 lr rifle barrel laying around somewhere from my rimfire days. I have no idea how many shots the barrel fired, but it was all subsonic target ammo, tens of thousands of rounds at least. There is a half-moon worn through the lands on one side from the slow action of gas cutting, not from cleaning. The smith who rebarreled it confirmed it with a bore scope.
Anyway, the rifle I am thinking of building is a .308 Win for long range and hunting. I also want to shoot cast bullets through it at about 1050 fps muzzle velocity.
