Sure Daryl, liberal use of a floating reamer would be required to clean out the bore up to a nominal forcing cone, leaving rifled chokes.

Twist rate is not as fast as some, but still way too quick for RBs at 1:28 right-hand twist.

A stumpy bore-gun is the most likely eventual outcome, especially if I can figure an easy way to make super-magnum LT-capped or Holland-style magnum nitro paradox projectiles, for which that twist-rate would be fine going by surviving guns from the period.
