What is the diameter of this slug?

I have a 12 bore David Petersoli 12 bore double express rifle that shoots beautifully with patched round balls.

I should be more that satisfied with its performance however am interested in shooting unpatched bullets from it.

One of the board members sent me a supply of Lee foster style slugs (thanks!!!) however they are a loose fit (maybe .03 to .04" slack) in the .729 bore and appear to be set up to shot from a shot cup. I have not had the time or courage to try shooting them.

It would be great to have a "minnie ball" style bullet that would shoot as well as the patched round balls.

Cheers,

Byron
