My main go to pistol is a Kimber clissic stainless gold match, 7 or 8 years old. I work from a large tub of federal brass, which I used to keep track of how many loading was on them, I quit countin after 8 loadings, that was 4 years ago. Still using same brass. My estimate would be 18 to 20 thousand rounds through the gun. Last year I noticed the rifleing wearing away in front of the chamber and switch to lead bullets to prolong the barrel life. I will admit that accuracy is suffering with jacketed bullets, but the 200 grain swc going around 750 fpt a still the bomb. I can nail an aluminun can at 30 paces more times than not. Not to long ago, I took a friend shooting, just for fun, we backed up about 80 yards and was ringing a 18 inch square steel target. From that distance, you would squeze the trigger, wait a second, think you missed, and the hear the ring.
