YABUT! You would need to get the lever-gun in .44 Special. Most are available in .44-40 or .45 Colt.
It seems from my reading that the most common "common" calibre in CAS is .45 Colt. it is available in '66s & '73s, AND in conversion cylinders and almost all revolvers. Note; also in Henrys, Marlins, & '92s.
For traditionalists portraying the post-1873 era, .44-40 has a following, as it ,and the .38-40, were the only calibres available in the early period that were common to lever-guns and frontier revolvers. The .32-20 came on a bit later.
Personally, I have settled on .38 Richard-Masons, and a Model '66 Win also in .38, and all by Uberti.
PS Dusty; I would LOVE to be able to get a Henry in .44 Spl. and Jacks carrier mod. In Canada it take ages to get stuff, usualy after the US market is satiated.
