I've been saving my pennies to convert my Single Six 32 to 327. David Clements (about $600) and Bowen (about $800) both replace the cylinder, shorten the barrel to reset the cylinder gap, recut the forcing cone, and reblue the pistol.
In another thread, Hondo44 responded to my comment:
While I am waiting for the reamer to arrive, I looked a little closer at the specs. The rim is 0.055". The 327 OAL is 1.275" min and 1.475" max. American Eagle 327 measures 1.467" OAL. I read on MarlinOwners forum that Single Six 32 cylinders measure 1.396", and the Bowen 327 cylinder measures 1.47". I get 1.40" when I measure mine, so subtract for the rim and there still could be as much as 0.018" of bullet sticking out of the cylinder!
Is this going to work? I'll let you know next week!

Hondo44 said:Simplest conversion there is. Just extend the chamber neck 1/10" with a reamer. Can be done by hand turning because so little material is removed.MacEntyre said:One day soon I hope to convert a Single Six 32 to 327 so I can compare.

Every single six .32 I've re-chambered shoots off the shelf spec length .327 factory loads!
So, I figured it is worth risking $100 to save $600. If it doesn't work, I can still send it to Clements.Hondo44 via PM said:Clymer's finishing reamer from Brownells for 32 H&R. They don't make a 327 but you just grind back the step at the rear end of the flutes the same length as the 327 case is longer than the 32 H&R; about 1/10".
The factory rounds will stick out the front of the cyl .002" to .003" but the cylinder to barrel gap is wider than that so there's no interference.
