Howdy,
Old post, hope your still around. I got one of these last year, I am not a hunter but it is a hoot to shoot.
The cylinder will fit the new army (uberti) so I have a total of 3 cylinders to share between them.
I use about 28-35 g fff and .457 ball (also have old army) use corn meal as filler and have noticed some kind of blowback that hits me in the left cheek, (got a beard so no damage) I suspect it is cornmeal since I think the cylinder is timed correctly and not shaveing lead. Another good reason to ALWAYS use shooting glasses. I read some where someone shot a pig @ 30 yards, in the ear!
Always gets lots of notice at the range. The gun not the pig.
Have fun
