Loading up some rounds for my new Sig Macro, my first 9mm - 125 grain coated lead round nose bullets by Gallant bullets. I pulled load data from my hornady reloading manual for 124 grain round nose copper projectiles - 1.150" COAL & 4 to 5 grains of unique. As far as I understand it, lead vs copper bullets are essentially the same cat. No load data on Gallants website.
Went outside to test fire a couple and they won't chamber properly. Extracting them from the gun is a real chore - can't believe how badly they get stuck in there.
I've done a little trouble shooting and am coming to the conclusion that my COAL is too long. I tried bumping it down to 1.110" and it still will not chamber properly. See below photos where I'm comparing some HST factory loads to my 1.110" COAL reload.
Checking diameters between the two rounds, they are consistent within .002", so that shouldn't be the issue.
What COAL should I be using for these?
Thanks!
