I joined the club too Jack!
Just before Christmas a friend told me about two Model 1867 Remington Rolling Block pistols for sale at a local shop, and was sad because the shop would only sell them as a pair! I told him I'd gladly buy one if he got both, and he did the deal!
(You need to Login or Register to view media files and links) (You need to Login or Register to view media files and links) The Model 1867 were all reworked Model 1865 Remingtons that began life chambered as .50 Navy rimfire. Just a year later the Navy asked Remington to convert all 6500 pistols to .50 centerfire, and the Navy began recalling all Model 1865's from service to be converted. They only returned 6358 pistols, and it took 6 years for the project to be completed.
As part of the conversion Remington added a new CF breech block, and a whole new lower tang and trigger that added a trigger guard the 1865 didn't have. They also shortened barrels from 8.5" to 7", and blued the actions over the original casehardened frames.
Both of these pair of pistols have minty bores, and mechanically perfect inside. They appear to have been just banged around a little from marks on the stock and forearm, but not fired much.
I'm building ammo from .50-70 cases shortened to .86" long, and fitted with a 300 gr. .512" bullet. Powder charges were originally 25 grs. of 2fg, so I'll experiment with something around there for loads.
