Last winter my son and I got into casting and powder coating some 5 k bullets (356-125-2R Lee) for our 9mm Glocks G43. I have an after market Blacklist Barrel for the reason i heard Glocks a picky with cast bullets. The bullet averages 130-132 and I sized before Pc and after. I am stuck on the Col or Coal in which i have to drastically reduce from 1.150 to almost 1.120 . This bothers me as my charge of 3.9-4.3gr Win 231 may have to be changed as well. The Col. of 1.120 seems to work in my plunk test of my barrel and it does eject and chamber, I am just not sure of the proper charge, I need a Safe Base Charge with the COL i am trying to use. If any help Please Let me know. Thanks oh and BHN of the bullet is around 15 maybe a 16. I use range scrape / Lyno and some hardball.
