I'm a piker, guys.
My T/C is in .357Maximum. 10" barrel, original sights. Used for production and standing big bore IHMSA. If the opportunity presents itself, I get some other barrels for it. Just haven't shot IHMSA in a long while.
I did fire my BIL's 45/70 years ago. 5 shots were enough, but I did handle it okay.
