    My Conversion of a Ruger Standard Auto .22LR Pistol to .25ACP is mostly done!
    John taylor of Taylor Machine in WA did the Machine work on both the barrel and the Bolt Modifications for a total work cost of $432.00 including finishing it in matching Blue to my receiver.


    The Modified Bolt Face. Note the enlarged Rim rebate to fit the .25ACP rim and the Centered round firing pin tip in the new Bored firing pin central position below the original Ruger rectangular firing pin tip channel. the 'lump above the channel is the Ruger recoil assembly forward tip and 'half moon' guide/stop. The Extractor works without modification. for reference the bolt assembly is slightly less than 3/4" diameter as it slides snugly into a .750" ID Drill Bushing I bought to use as a Ring Gauge.


    The top view of the Bolt with recoil assembly removed to show the new firing pin in its channel. Just visible is the 'Trumpet' shaped transition form rectangular cross section to the round section tip going into the new centered port and the old tip channel for the Ruger firing pin.


    Left side of Modified MKII pistol with its new 8-1/8" Barrel. The 'white' bare metal band on the muzzle is where i turned off the Muzzle threads. I was informed that threaded Muzzles are Now Forbidden in California due to new legislation by the Democrat Controlled State, County, and Local Governments. Sad State of affairs now.


    Right side of Modified MKII pistol with its 8-1/8" long Barrel. Currently it is still a 'Single Shot Auto Eject Pistol'; as i do not yet have magazines to fit its grip frame and feed .25ACP cartridges.

    I have Purchased an adjustable rear sight to replace the original fixed rear sight, but it is yet to be installed.
    To date only John Taylor has fired a round through my converted Action, using his grip frame under my Receiver/Bolt/Barrel combination. I hope to get to an Indoor range soon to do some 'single shot' shooting myself.

    These Photos were taken by my Special Effects Business owner Friend with a Camera that has a "Macro" Photo Capability.

    I have been 'pondering' on using .25ACP cases to make a more modern, or updated, version of the .221 Atkins and I believe it is a reasonable idea.
    - The rim diameter and thickness is closer to .22LR than that of the 5.5 Velodog Col. Atkins used as the 'parent case.
    - I know the .25ACP can be swaged down to .250 body diameter reasonably. I have done it using Drill Bushing derived Dies, and the .25ACP extractor clearance cut makes removing displaced brass 'rings' almost easy.
    - The rim could be turned down in diameter to match .22LR if desired, but a center fire conversion of a 22LR bolt is relatively painless with suitable tooling and opening it to accept the ACP rim would be trivial.

    Something for further Thought I believe.

    I made a little progress on my efforts to make some reloadable 22LR!
    I bought a 3 cavity 22 cal 37gr mold from a member here and cast about 150 boolits!
    Sizing and lubricating is a challenge, I had to use tweezers to put hem in and take them out of the Die!
    Sure can make a bunch of them from a pound of lead!
