I have 2 Lymans/ The Great Plains which is a 1 in 60 twist and the great Plains Hunter which is a 1 in 32 twist. My Great Plains round ball gun is as accurate as any gun I have. It is my favorite as far as a traditional gun goes. It shoots round ball and even conicals. I can shoot a T/C maxi ball or Great plains conical or Buffalo ball-et with a wonder wad and it usually hits the hole of the round ball shot. If you are getting the flintlock I would stick with the 1 in 60 twist and definitely a Lyman over any other brand. Just My opinion. Keep in mind that i'm biased because I started out in 1980 with a Lyman I built from a kit. So naturally I'm partial
