I have a Savage .308 Winchester barrel and wonder if it is feasible to cut and rechamber to 7.62x39. If cut short enough to recut the chamber, would there be enough exterior threads left for the barrel nut?

I think problems you'd run into is the current bolt head would have to be changed, magazine probably wouldn't feed the rounds reliably if at all. Completely removing the 308 chamber area wouldn't leave enough threads, if any.

I wasn't sure if too much metal would have to be removed. I didnt think about the feeding issue. I was going to get a PTG bolthead if it would have worked.
Won't work. You would need to cut 1.5" off the tennon.
Use a Remington 308 varmint barrel.
I recently rechambered 2 3006 barrels to 30tc, had to setback the threads .50" and add 10 more threads. Most savage barrels require .625 inches@of threads from breech face forward to correctly headspace and still have room for the nut, all depends if you use@a standard recoil lug or a thicker aftermarket lug. Normallycase head or headspace gauge protrusion is .120 to .135 on cartridges@that use 308 bolt head
So why rechamber to that round? Common caliber with other rifles? Cheap ammo?
I only ask because I bought a .223 thinking it would b e cheaper to shoot. Then decided I liked better accuracy. Then found out I couldn't afford to shoot factory match ammo. So, now I reload for it and shoot the 'good' bullets.
Seems a .308 will do anything you want while the smaller cartridge is limited.

The Dunning-Kruger effect is alive and well.
Randy is dangerous with a hacksaw !! LOL
And Randy !! A new version of the .284 is in the lathe as I write this.

Makes more sense now.
