Major brain fart for me this morning. Ever wonder what would happen if you loaded the wrong bullet? After 30+ years reloading I found out. I loaded 6 rounds of what I thought was a new load I cooked for my New Vaquero 45 Colt. Bang, bang, and bang. No recoil to speak of, bullets were on target about 2 inches apart, keyholed. I extracted the spent shells, bulged and split. THEY WHERE 44 SPECIALS LOADED WITH 7 GRAINS OF HS-6 AND MAGNUM PRIMERS!! I'm always the first to admit a mistake, I'm just glad they were light loads and not magnums, as the New Vaquero can't take a lot of pressure. See pics of 45 and 44 special.
