Without cleaning the gun until last night, I had shot 1,250 rounds of boolits through my Glock 23, this over a couple of weeks on occasion. Using Lee TL401-175-SWC with 95pb/2sn/3sb alloy air cooled and lubed with 50lla/40jpw/10ms and left to cure well. The propellant was TrailBoss and the load worked-up with the manufacturer's alternate directions, it is a mild for 40SW loading and I have not bothered to get the chrony out to clock it. I did check the barrel visually with bright light before each session, but never saw any reason to worry. Last evening it took about 4 Ed's Red soaked patches to get all of what appeared to be boolit lube residue out of the bore. I did get a tiny glint or spec of lead on the second patch. With the bore looking pristine clean, I than used a bronze bore brush and Ed's Red to scrub it vigerously and then ran Ed's Red soaked patches again with the third patch clean. No evidence of lead. From now on, I will do my first cleaning patches soaked with mineral spirits to more easily get the boolit lube residue out. I get more lead than that in my Ruger BVs if I shoot smokeless propellant. I think it is all about boolit fit and not mashing the boolits out of shape with a too tight crimp or final size die. YMMV always proceed or retreat with caution.
