I have a 7.7 to go with the 6.5 , a 32 Rem , 11mm Chessipot , 45 S&W .
Not invisible so much as not popular I guess .

The 32 Rem shares data with 32 Win Special but it looks like a rimless AI with a Weatherby shoulder and about .03 shorter .

The Chessipot is a paper cartridge bolt action single shot . Mine has an 1871 issue stamp on the stock . Lots of information available just not on an average Joe level .

45 S&W aka Schofield isn't really an oddity load data boils down to 45 ACP data in a 1.10 case length , shorter than the 1.28 Colts . I don't have a Schofield pistol but I do have a bubba'd 1917 S&W reamer to head space the Schofield case on the mouth . So it will eventually get some P+ loads . Which sounds bad but the OM design is for a 12 kpsi cartridge and I plan on hopping it up to like 18 kpsi ......a 250 gr SWC about 950-975 fps in a 5" DA with target sights . Well inside the 21kpsi design of the 1918 built N frame .
