I have done the re-chamber on M 30s and M 31s several times. I will do that rechamber job for any member of this forum on either model for $75 plus return postage. I need the cylinder with the extractor. I will not rechamber any other model of handgun that shoots 32 Long. ..........

And, yes, you can still shoot 32 Long in a rechambered cylinder. I do not recommend a steady diet of the 32 H&R Magnum with the heavier grain weight bullet. ...............
