.454 Casull Lever action. Can also shoot .45 long colt if you want.
Holds 9 rds of .454, and 10 rds of .45 lc
This is an older puma M92, which I believe is basically the same as a newer R92.
you can load via the side load gate or feed tube (some of the newer ones you can’t load/unload via the feed tube).
I haven’t used it much (less the 200 rounds), and haven’t shot it in over 10 year, but had not problems loading .454 casull or .45 LC (with the exception s the Corbon 360 Grain Flat Nose Penetrator which shaped like a brick.)
Compared to revolver, add about 250-400 fps to what listed on a box of ammo. This makes a great bear gun. Due to pressures of the .454 and the barrel length it very close to a .450 bushmaster and not fare from a .45-70 but more capacity.
