Can't say about that T/C barrel. Oughta be good to go though. You'll have a 50gr. heavier roundball with the .54 to send out there. Might even try some conicals and see what they shoot like. I've been casting .527 roundballs, .530 roundballs and the 420gr. Minie' in that particular caliber lately. Could send a handful of each your way to see what it likes.
