boring out a barrel

[Pioneer flinter]

I have a 13/16 barrel I was thinking of having Bobby Hoyt boring out to a smooth bore. What would be the largest caliber he could do on this barrel? If anyone would know? Thank you all.

Why not ask Mr. Hoyt...?

.45 to possibly .48. I think it’s too small for .50.

Depends on a few things like , what kind of steel is it if it is steel and what do you intend to shoot in it.
You need at least a 3/16" wall at the breech if it is good steel.
