: .22 cal barrel?
: rkr June 08, 2009, 11:34:06 PM

Is 22 cal air rifle barrel the same diameter as 22 lr rimfire? I.e. could I just chamfer one and use it with 22 lr cartridges in place of a regular 22 lr barrel?

in a word, NO, the rim rifle barrel has a larger bore than the air rifle barrel, will cause excessive pressure, also the air rifle barrel is mild un hardened steel, pull the trigger with a rim fire load and it could go boom....twist rates are different also, it's big no no...

Oh well, back to the drawing board. Thanks!
