    Rim Diameter od .25/.27 ramset cartridge

    I have some .50 cal rimfires carbines. Love to shoot them. I have used brass avaiable from Dixie, but they are out and don't know if they will ever get them again.

    Found some nicely made brass that use .22 blanks for the primer. But my firing pin doesn't strike the rim of the .22 blank.

    Thought what about using a .25/.27 blank for the primer so that firing pin will hit the rim.

    Does anyone have a .25/.27 blank and can get me a rim diameter measurement.

    Thanks in advance.

    Thanks, that would give .03 extra width. Could be enough.
