Get 2 or 3 brands and test them. There will most likely be a clear winner, at least that is my experience with slugs.
Only you can decide on effective range.
Betting it will kill farther than you can accuratly shoot with a plain bead.
Fixed choke or screw in tubes?
Screw in tubes.
The gun was manufactured in 1932. The S/N says it was one of the first 500 made!
The stamping on the barrel revealed that it wasn't original to the gun.
I don't know if there was more than one barrel or the original was damaged beyond repair.
Since the barrel wasn't original to the gun, I sent it to Briley in Houston and had it threaded for tubes.
Their basic service gives you three tubes.
I got X-Full for turkeys, a tighter Mod tube and a tighter Imp Cyl tube.
I'm using the most open tube.
Tried a couple of slugs at 25 yards. Guestimated a sight picture.
First one hit 1.5" high dead above the bull. I pulled the second shot, but it would still be a killer shot. Dead o.n horizontally and 1.5" right.
Got plenty slugs. My shoulder withstood two slugs just fine. A prosthetic shoulder can't handle that much abuse.
