I have the F. L. Lippieta 1858 New Army .44 caliber target model revolver. I bought it from Cabela's. The revolver is a lot of fun to shoot. 25 grains of Goex 3f and a .451 roundball and wonderwad, this thing will really shoot. It is not something you're going to rapid fire because you have to cock them careful to avoid the caps jamming up, but it sure is a blast. I squirrel hunt and bunny hunt with it sometimes, but mostly target shoot.
As they already said, these revolvers are a pain in the you know where to clean. A friend of mine said he takes his, removed the wooden handles and runs it through the dishwasher. He said it comes out HOT and CLEAN, then he oils it up after it cools and puts it all back together. I have not tried that due to the lack of a dishwasher..

but I have pulled the handles and washed it in a bucket of hot soapy water, then run solvent patches through it and oil it all back up and it works fine.
If you are not an avid shooter, you might be better off with a rifle. They are easier to clean and just as much fun. Unless you like the mess..
