Can a S&W revolver chambered in .32 Long be reamed for the .327 Federal load? Or, as I suspect, is the cylinder too short?

I have a Model 30-1 with an extra cylinder bored to 32 Magnum. It does not appear long enough for the 327 Magnum. You could sleeve a 357 magnum but I would be afraid of pressure issues with the sleeve.

You don't mention which revolver in 32 S&W L you wish to rechamber to 32 H&R. I'm not sure I would make an I frame into a 32 H&R due to its age and the size of the cylinder. OTOH, a 30-1 or 31-1 should be fine... it's been done (and the results discussed here) several times.

If you are talking about a K-32 in original 32 S&W L chambering, it would work of course, but the loss of value of the K-32 would be more than I would be willing to give.

What do you hope to accomplish with the alteration? Also, do you reload? If you can roll your own, you can get H&R performance (or close to it) from judiciously warm 32 S&W Long reloads. I even load somewhat "warm" loads for my 1949 vintage Transitional 32 HE Snub. It digests them fine and hits as well as I can shoot it.

No problem with 32 H&R Mag on a 30-1 or 31-1 which is a J frame. The H&R is not really a "magnum" per se with it's ~ 19,000 PSI. I've done that.

But the .327 Fed Mag with about 35,000 PSI is another story. I would only do it with a factory J frame .327 Cyl and it won't be fun to shoot!!

If you reload, I'd do as Green Frog suggests, load up the 32 H&R.

The Max pressure for a 327 Federal cartridge is 10,000 psi higher than a 357 Magnum.

Thats 45000 psi.

I wouldn't want to shoot that in a reamed out older revolver.
