Hi guys, this is my first post on this site, been checkin it out for awhile but had no reason to log on, but I can offer some assistance as far as rifling on the Cabelas blue ridge, I have a 50cal flint, it shoots vary good, the groups are pretty good for me, I'm not the best flintlock shooter around but this gun is a good sparker and ignition is pretty quick, so even I don't do to bad with it. the rifling on mine is vary deep, at least .010-.012 deep, so it shoots a thick patched ball pretty good. you'll like it its a darn good gun, but the price has gone up alot since i got mine.
