SHOOT 17M2 & 17A OUT OF YOUR RUGER 77/17or22WMR - Jesses Hunting & Outdoors (JHO): "TECHNICAL NOTES)

Clerke machines a .007' thick shoulder on the breech face of the barrel to make up for proper headspacing of a 22 LR case fire with a 22 mag bolt.

I also modified the cartridge support to improve the extraction because the cartridge support was originally tuned for 17 HMR (22 mag case). Once this mod is done, extraction and feeding is better for all rimfire calibers.

You can also use stock 10/22 magazines in the 77/17 or 77/22 magums by installing an extended magazine latch plunger instead of installing a spacer on your mags."
