RJM: I measured my stainless 22 L.R. cylinder and it came to 1.401" "long"!
Then I measured a Winchester 22 WMR cartridge I have at my house and it came to 1.382"!
Or a difference of only 0.019".
Then I measured the case head recess in the 22 L.R. cylinder and it was 0.040" deep! So if this pistol had a 22 Magnum cylinder ever and the cylinder was 0.040" recessed the cylinder could NOT rotate as the bullets would be sticking out the end of the cylinder and they would come in contact with the barrel before it would be aligned with the bore - would they not?
The cartridge I used at the store for comparison was a "polymer-tipped" 22 WRM cartridge and it was longer - I am sure - than the cartridge I have at home which has a hollow-point flat tipped bullet.
Thank you for the insight and tip on the Ruger Forum, Bob!
Could I trouble you to measure the cylinder on your "starred" pistol?
My frame has no star that I can find?
Thanks again.
Hold into the wind
