A BP revolver can be fun to shoot!
The Old Army is a great revolver!
I've owned one and it was very accurate & dependable.
However............ they can be a pain to clean, and if you don't clean them thoroughly they can have a variety of failures. [:@]When cleaning any BP revolver I use a small metal"blueing tank" (about 6" wide, 6" deep, and 18" long). I disassemble as far as possible, clean the cylinder and barrel, then put everything but the wooden grips in the tank with water (& soap if desired) andheat on my camp stove.When good & warmremove the parts, wipe them down, and replace them in the tank in fresh water. Bring to a boil - remove & dry the parts - then oil well. Maybe a bit over-kill, but I never had any rust problems!
