i:32 is a conical twist, for those super duper $4.00 bullets the in-lines use. It will still probably do fine for light load plinking with a tight patched round ball.
We routinely start folks out with 50 cal muzzleloaders with 30 grains 2fg and PRB's.
BTW, I understand that CVA made a small production run of 36 caliber barrels for the Bobcat "platform" In the past year, I saw only one for sale on-line, but keep your eye open, you might find another barrel for it. It also would not take much to make a drop in barrel for it. The button breech plug shape is easy to duplicate.
