I like the 1851 Colt Navies in .36. One time many years ago my son and a friend were shooting their wonder 9's. I picked up a Navy and loaded it, stepped out of the back door and shot their target. 5 rounds in a clover leaf, they put up their guns. Never had a Navy shot that good before or after. It was fun though to see their face, as it caused my son to put a lot more time into trying to beat dad's target. Today he knows it was just luck and everything coming together but as a teenager he thought I was that good. Today I am 75 and have been shooting black for 65 years. Much more fun than smokeless!!!
I recently picked up an old beat up CVA Hawken, did some work on it, and now i have a shooter. Really want a single shot BP pistol though....have to save my pennies I guess.. good luck with you gun!!
