Got one similar off a member here, Firehawk .58 blued and walnut that is a nice piece. 1in 38 twist. It shot best so far w/260 grain Speers in 45 cal saboted with 80-90 grains ffg. Yours is a 50 so may differ. It didn't like conicals that well and neither did I. Really like the thin wrist on the stock. Mine wears a fixed 2.5x scope and handles well. A little chore to clean but worth it.
