Hi everyone, I'm an IPSC shooter from Argentina with a major concern... I have a Briley Bull Barrel .40 with approx 30,000 rounds through it with an Aftec extractor. Recently the brass has not been extracting and jams my gun.
My gunsmith tells me that it's because the barrel chamber has deformed. The grooves are perfect and the gun still shoots sub 1 inch groups at 25 meters. My question is:
1. What is the life expectancy of a barrel
2. What is the life expectancy of an Aftec extractor?
Thanks guys!
