Heavy barrel

[hepburn4590]

Check with PacNor for the barrel. If I'm not mistaken they can go to 1.400 dia. They offer the twist you want. You will have to cut your own flats on the barrel. I've done a couple or few of these false muzzles using a piece cut off the barrel to be used. Use Cerrosafe to pour the arbor for aligning the rifling. Clamp the faced parts together using the Cerrosafe plug. Drill the dowell holes with it clamped together. I use a index chuck to clamp the pieces together. Your alignment will be perfect. This will be a fairly simple task given your background.

Does anyone have a copy of Lester Cox's instructions on making a slug gun?

Some of these guns like to be rested well out toward the muzzle and a 48" barrel requires a pretty big bench or clamped on extensions. They are also a bigger PITA to load unless the shooter is about 7 ft tall.
Shooting heavy bullets barrels this long may not be needed. If I were making one I would not exceed 36 to 40".

I wanted 40 to 48" to start with so I could use the extra length to make the false muzzle and bullet starter. The finished barrel would be 32 to 36" long. Rice barrels said they can make me what I want. Still doing my homework. Thanks.
