I agree. The only concern here is finding a spare K frame 22 cylinder, reaming it and fitting it. The pressure of doing this is .00000000nothing.

Oversized bullets only blow up guns when coupled with other factors. Gross head space, gross overload, a poor cartridge to chamber fit in some manner that lets pressure out in the wrong directions.

Something like a .318 bullet loaded in a 30-06 might be a problem, but, not because of bore diameter. But, because of the chambers neck and throat diameter clamping down hard on the neck and bullet base because of the increased diameter in this area and making it difficult for the bullet to start moving.

As stated read about some of PO Ackely's experiments. A .224 bullet in a .222 bore is basically a non event.
