Home depot, RONA, etc. They have the Ramset charges which are simply short, crimped .22 blanks.
I thought i heard somewhere that these things *might* be higher pressures than a standard .22 cartridge. While i cant see a blank cartridge being a higher pressure than one with a projectile, i would make sure that they were "rated" as it were for your firearm. No sense in ruining a perfectly good barrel (and face) with a blank not meant for your regular every day firearm.
