anybody know about this rifle?

[Cattman]

about 15 years ago a friend at work gave me his dads percussion 45 cal side lock to clean up and put a new nipple on. it was a cabellas thompson hawken look a like. the first thing i noticed was it has 12, yes 12 lands and grooves. no more than 3 to 4 thousands deep on the grooves. i even think it was a 1/60 twist. after cleaning it up and putting the new nipple on i shot it at 100 yards, it was deadly consistantly accurate. with any load it shot a patched round ball in a tight group at 100 yards. anybody know about those guns and the 12 lands and grooves in them? i always wanted to get one of those as they were well built and most of all very very accurate. it has always been on my mind to find out about this gun.

I would suggest posting a photo so you can obtain a decent answer.
