So, back when FA was trying to convince the world that the 454 Casull was the only pistol round worth spit, John Linebaugh, John Taffin, and a couple of other Johns convinced them that not everybody was ready to run out and buy rifle primers. The result was a very short run of 44M and 45LC pre-M83 guns, including my new purchase, one of only 54 "Casull 45 Colt" guns ever sold. She shoots. I launched 150 300gr over 26gr H110 from it on Friday. Easy to tell where the misses hit the berm at 200m!
