New to me navy arms

[Garbear34]

I got a navy arms 12 gauge. Just getting around to playing with it.

Ive read vm starr on muzzloading shotguns.

Right bore near as i can ascertain with calipers
.725

Left .719

Im wondering what choke on the barrels. Looks chrome lined. Hoping pattern it this weekend

It looks to be made by Pietta. I've never actually held one, but they are nice handling guns by reputation. There is little or no choke in those barrels. If there is choke, you will be able to feel the change when pushing a wad past the constriction of any choke. I hunt with cylinder guns regularly, and it's really not a problem, sometimes even the long shots work (go figure).

I bought one new in1986 for $329.xx. Both barrels are cylinder and shoot just fine. A very nice handling SXS.

Thank you. It shoulders great for me lines up on the bead. I need to pattern it. I have a .69 round ball. Guy i bought it from gave me plastic shot cups for 7/8 oz and 1-1/8 oz. Planning not even bother with those. Figure start with 60 grain powder and 7/8 oz shot. Have 8 shot size and 5 shot. Have tons of .31 round ball either way going to be fun. From scouring posts cylinder bore on these. Any load suggestions be apreciated and patterning distance be appreciated. Im thinking pattern starting 30-35 yards probably me the max effective range of cylinder bore.
