Can I shoot a round ball in my 12 ga. Navy Arms Double barrel shotgun?

I brought home a dial bore and checked the bore 5" down down on each barrel, one bore checks .725" and the other checks .726" and tapers to the muzzle to .751" and .768"

I think I might try loading with just a 12 gauge wad and seeing how tight it is going down each barrel before using a ball that is over .715

Balls, wads, and over powder / over shot wads on order tonight.
