I have Range Lead and it's at 10 BHN with water dropped as I haven't checked after couple says so may harden couple. Anyways my glock 17 is slugged at .356 so I sized at .357 and smoothed bored within couple rounds. In using Red bullet lube that's for hi velocity rounds and very bad experience. Anyone know how to fix this issue? Iv tries Hi-Tel with horrable experience. Only lead I have is Range lead. I shot these also out of my Sig MPX with leading on the lands but nothing like my glock. Would this work ok in a glock 21 .45 acp?
