Wow close to 98 lbs a year. About 5 times what I shoot !So far in the door and the barrel 3,299 pounds of bullets I have casted.
( using 158 grain as an average)

One of the best CBA military shooters has a documented 25,000 linotype rounds through a used 1903 barrel. Cartridge overall length has increased almost .250" to just touch the rifling. Fiver has a good handle on the issue.Is it really even possible to wear out a barrel with cast bullets?
I don't think anyone could if the GP100 was taken care and only shot castI've speculated on what it would take to wear out a GP100 from use (not abuse). I can't really imagine what the round count would be. I know I probably couldn't afford the ammo bill!
I believe he always used 22 grains of 5744 with a 200 grain bullet. MV was 1600 f/s.I doubt I'll ever be able to afford that many primers again, but it would be fun trying to wear one out. Any idea what kind of load with those linotype bullets did it? I tend to load things very mild most of the time.
Using a 230 gr RN or TC, pushed by 5.5gr WW231, a barrel lasts about 50k rounds. In the course of shooting out several barrels, I replaced a couple of firing pin springs, an extractor, the thumb safety, maybe 1-2 other small parts. I had a Dwyer Group-Gripper in the gun, running a heavy recoil spring. I replaced the buffers and recoil springs periodically.I've read about 30-30s being worn out but with the millions of ACP family guns out there nobody has ever said "I had to drop off my P35 and 1911 , the barrel was shot out " . It's always slide and locking parts .
