7.62mm x 25mm REVOLVER
I have long been a wheelgun fan and am interested in a revolver in 7.62 mm x 25 mm. Does anyone make such a critter?
A machinist friend suggested taking a cylinder from a Super Blackhawk, put in sleeves to convert it to 7.62x25 and fitting it in a .30 carbine Blackhawk. [easy for a machinist to say, personally I'm lucky to get my M1911 reassembled.]
Opinions?

You (an accurate machinist or toolmaker)could do that but the cartridge is less powerful than the 30 Carbine. Be aware also, that surplus 7.62x25 ammo is corrosive.
There is the chance that being a bottle necked cartridge, 7.62x25 cases may set back and prevent the cylinder from turning.
50 years ago I did the opposite in converting the PPSH41 submachinegun from 7.62x25 to 30 Carbine and used a 50 cal BMG driving spring. It was a mixed success because the higher pressure carbine round really needed a locked breech so it split a lot of cases. When it fired you couldnt tell if one or twenty rounds went off.
At that time I also converted a 1917 Colt 45ACP revolver to 30 carbine using bushings made from 30 caliber barrel and a barrel made from a piece of 1917A1 water cooled machinegun barrel. This is another non recommended project because the frame started to stretch after a few rounds.
Experimentation is a sporting proposition where you have to accept expense and be prepared for failure. I would start with a 45 caliber cylinder and press fit 7.62x25 inserts into the unaltered chambers. If the project fails you can press out the inserts and sell the cylinder.0
