I made it to the range with my MkIV Saturday. I loaded 3 rounds, 1 CBC 24 ga brass with 60 grains of Goex 2F, dryer lint, card wad, wool wad, card wad, grease cookie, 2 card wads and a .468 dip lubed RCBS bullet, case neck sized only and lightly crimped. 2 Jamison brass, same load. From the bench, 100 yards.

I had 4 rounds of the .468's left and decided to try my luck off hand.

Clean up was a breeze compared to my experience shooting all black in the past. One hour and I had the rifle and brass clean.
