Many gunsmiths can but will they ? I was talking with Hamilton Bowen years ago at a gunsmith school about this very subject. Bowen is all about custom cylinders and swaps but he pointed out that for liability reasons it’s not a smart move to re-bore factory cylinders especially when you would roughly be doubling the working pressure from 22 LR to 32 H&R. Not to say you’d have problems but it’s not a smart move on the gunsmiths end.

Good luck
