Anyones help will be greatly appreciated.
I am loading 9mm & 45 ACP. I am using both Blue Dot & W231 powders for both. and with each of these combinations I am getting deadly accuracy, but I can't stand the BLACK SOOT bulding up inside my guns, not to mention the amount of soot on the outside of my cases.
I have completed everything methodically as far as excellent reloading practices. Tumble, clean primer pocket, brush inside cases, carbide size, chamfer case size, CCI prime, ensure my case length is consistent ~.0005" less than maximum allowable tolerance, powder charge, then seat a bullet (snug to tightly as I cannot budge with my bare hands), and I cannot get rid of this soot!!!!! It's gumming up my semi's in a bad way after 6 or 7 mag fulls!
Loads I have tried:
.45 ACP - 230gr LRN - 7.5, 8 & 8.5 gr Blue Dot
.45 ACP - 230gr CMJ - 4.2, 4.6 & 5.1 gr W231
9mm - 115gr CMJ - 3.5, 3.7 & 3.9 gr W231 - (Already seeing signs of extruded primer surfaces at the 3.7gr level ???)
Is my brass expansion he problem? Do I chance going higher then recommended loads? Help is greatly appreciated at this point.....
