On November 25th I started the Process of converting A Ruger .22WMR 'Single Six' Revolver to chamber and fire .25ACP and 6.35x28.6mmSR Cartridges.
I already had a 'replacement 8-Shot .22WMR Cylinder' (purchased from Numerich Arms) reamed and chambered in .25ACP to see if it was Feasible. The .25ACP is .276" body diameter compared to .22 WMR's .242" body diameter.
It turned out the "Ruger" Rim Rebate is large enough to fit both a .25ACP rim at .304" and a 6.35x28.6mmSR rim at .314".
The cylinder measures 1.405" in length at the Chamber center Line, from 'Breech face to front of Cylinder Face, ignoring the Ratchet and front 'bush' extensions.
On the 25th I completed Purchase Arrangements (in California) for a Ruger .22 Caliber Single Six fitted with a roughly 6" plus barrel, Beginning the 10 day Waiting Period for delivery.
I also Dropped off a 'horded' Lothar Walther ".25ACP/6.35 Browning" C-M Barrel blank about 1.1 inches in diameter and 23.6 inches in length, having a one turn in 9.4 inch twist rate 6 groove rifling. "American Gun Works" in Glendale, CA is doing the conversion work. The Ordered Barrel will be 10-5/8 inch long. forcing cone to muzzle so the 'overall SAAMI length is about 12 inches, when the Cylinder length is included.
Also I ordered a Second Cylinder from Numerich Arms, for reaming to 6.35x28.6mmSR chamber Dimensions and eventual fitting as an interchangeable Cylinder in this Project Revolver.
During the ten day waiting period my gunsmith intends to cut a 12 inch 'Blank' from my LW Blank; then begin the Contour turning between Centers to reduce the 1.1 inch to near final diameters. As he has on hand a "Take off" Ruger Barrel, he can turn the Barrel blank to near final Tenon dimensions also.
Work that will need to wait until the Revolver is Delivered to me includes:
- Removal of Existing .22 Cal. barrel.
- Dismounting of Barrel mounted front sight for transfer to my New barrel.
- Dismounting of the unloading rod, housing and mechanism to fit to my new barrel.
- Fitting and timing a new Pawl to index the 8-shot Cylinders.
- Fitting Both cylinders to the Action.
- Fitting the New Barrel to the action.
- Installing The front sight on the New Barrel.
- Other Miscellaneous finishing work.
Eventually I will have a rather Unique Revolver, for both 'plinking' and 'Target' shooting, in two Cartridges of little General use in Revolvers.
This will go with some other "unique" firearms:
- A Stevens Favorite converted to Center Fire and fitted with a Stevens ".25 Stevens" Barrel which can chamber both of the cartridges in plan.
- A Stevens Model 44 Converted to Center fire and having both a Stevens "25.R.F." Barrel with chamber reamed to ".250ALRM" and a Stainless Steel ".32 Long Colt" barrel.
- An Iver Johnson Revolver in .32 Long Colt (also being reworked by AGW).
(Cartridge Cases That is.)
