Single shot barrel work?

[pharmboy]

I've got a single shot .357 I'm going the SBR route with, and I'm hoping to find someone local to cut, crown and thread it at 10.5" with a longer than usual 1/2x28 thread so I can use a 3/4x10 adapter to mount my old 2-stage Sionics can from my Mac. Anyone here know who might be able to take this on? Picture included of the rear of the barrel to show what I'm working with. Thanks in advance.

Diamond Collision owner in Avon. Does fine work but I am unsure about turning Encore/Contender style barrels. Send him a msg.

1/2-28 threads on a .357 bore leaves less than .050" of steel at the root of the thread. 5/8-24 would be the better choice.
