I use a 650 Dillon, all my tool heads have Dillon powder alarm die or the rcbs lockout die. I also use cfe pistol in 9mm,38s,40, and 45acp. It fills the case nicely and double charges will be up to the brim. Lastly 9mm glocks are supported, at least as much as any other 9mm auto. Their 40 and 10mm have the least support, but still as much if not more than 1911s in 40/10mm with non ramped barrels. I will never own a colt in 38s/9mm or 10mm, they make smiley cases that show up glocks, lol. Glad your safe op and didn't lose any fingers.
1) super glad OP is ok!!
2) I run exact setup as 6brahooter; Dillon 650 and cfe pistol. Hard to double double charge with this powder.
3) agree it is most likely double charge, for what my opinion may be worth?
