What explains the soot on fired shotgun hulls?
After 125 rounds at Trap, my Winchester AA previously fired, handloaded hulls were so dirty my right palm was completely black from extracting and placing them in the rear compartment of my shooting vest. The same was evident on the extractors of the shotgun. I was using 800-X and Red Dot with loads producing 1200 fps with one-ounce of #7.5 and #8 shot.
