At Heluva Rukus, I offered to let Tex (SASS#4) shoot a few of my short colt 777 rounds. He commented to one of his pards "he's tryin to get me to blow my guns up" with a grin.
Undeterred, I said "oh, i see yer shooting Colts, let me git ya a real gun to try em with, one of Uncle Bill's guns", and handed him a vaquero.
With another grin, he loaded em up and gave em a try.
Just gotta luv it, when a man is skittish of a round till ya hand em a Ruger.
