If you don't get a response, I'll bet a call to Mr. Bowen's shop would give you what you're looking for. His catalog indicates the phone hours are 9:00 AM to Noon, and 1:00 PM to 6:00 PM ET, Mon-Fri. The number is 865-984-3583.
I suspect you may be familiar with this information, and if so, apologize for the redundancy.
When you find out the answer (if not available on this forum) please post the information you find out. The more I think about these handy pistols, the more I think about getting one. I've been considering the 32 H&R, but something in me says to go with the 32-20. I'm sure Mr. Bowen's shop can do some type of conversion to work, but not sure if a rebore is what's needed.
I did some digging on the web and on sixgunner.com there was a review by Paco about the .32-20. He has a couple Rugers and Smiths with extra cylinders in .32-20. So yes, it is possible. Just need a shop to do it. I am going to call Ogelsby & oglesby tomorrow. They don't have a web sight. I saw a good report on them in 2002 Guns annual. I like the idea of the "classic" caliber. But it would be nice to have the dual cylinders too. Then I could shoot .32 H&R Mag and .32-20!
I'm pretty certain this can be done to a Blackhawk, so it wouldn't be a re-bore. Looking at the pair of .32 single six revolvers that I have, it doesn't look possible to make it work on that frame. I have a 32-20 in a Buckeye Blackhawk with the additional 32 H&R cylinder. The 32-20 can be loaded safely to exceed or equal light bullet loads in the .357 Magnum with ease. The Blackhawk is a lot of gun to carry around to shoot the .32 H&R, best left to the single six in my opinion. Depending on how much cash you want to part with, the best solution might be to try and find a NIB or used Buckeye conversion like I have. No matter what it cost you, within reason, it's going to be a lot less expensive than a new cylinder/barrel for a blackhawk plus the cost of the pistol to start with.
I recently asked the same question on another site. I finally got an answer from a guy that said he had reamed a .30 carbine Ruger cylinder to take a .32-20. I think the .32Mag. and .22 are on the same frame and if they are then the .32-20 round is about a 1/4" too long, from the measurment of my single six cylinder. I was wanting to do it but all .30 carbines have 7 1/2" bbl. I was wanting a Birdshead .32-20. I guess if I had wanted to do it bad enough I could have bought a .30 and asked Ruger to let me send it to them for a birdshead grip and 4 5/8" .32 mag bbl. Then get the cylinder reamed when I got it back. All that was more time and trouble than I wanted to put in it. Hope my rambling has helped, JTT/NC
