Here are the ML I have in the order I got them.
Cabelas .54, 1:48" Hawkens made by Investarms, extra drop in barrel from GM .45, 1:28" twist.
Pedersoli full stock Pens. in .45, 1:48" twist
Hopkins and Allen Underhammer New version .50, 1:66" twist, 26" length. Extra .45, 1:66" twist barrel 32" lenght.
Pedersoli 12 ga. double barrel shotgun.
Hopkin and Allen Underhammer Old version .50, 1:60" twist 36" Douglas barrel so I'm told.
Forgive me if my memeory is a little off on the twist and length. Too lazy to dig them out of the safe right now.
A .60 smooth bore barrel is on the way for my Hopkin and Allen frame thanks to Fred.
