rechamber to 7.62x39

[xtratoy]

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?

[GaCop]

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.

PT&G PPC or Savage 7.62x39(.448) Bolthead

Prefit or savage 7.62x39 Barrel

Adjust firing pin protrusion if needed

That's it.

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 3006 barrels were tomato stakes and i cant take their recoil.the reason for that vcaliber was i had the reamer. The new chamber accepts 30 tc and 308. With a wide assortment of barrels to choose from the convtsion of 06 barrels lets my inventory be more useful.

Makes more sense now.

I remember you posting about this a while back and wondered what barrel profile you had. Most of my barrels, even the varmint and bull barrels if I remember correctly, don't have enough meat to move 2"s back and still have good thread engagement.

Robin the barrels i set back are all standard savage sporter profile and only one was set back more than 1/2 inch. I like to end up with 1.625" of thread to accomodate the nut.

Porter Cable Cut off. I like them pretty colored sparks, or with
some stainless steels, the lack of. That SA284 test barrel is now
a .284ELF test barrel.

My high speed steeladjustable thread die serves as a guide for the hacksaw blade to make nice cuts. Also use it as a file guide when dressing up the hacksaw cut. The saw or file will not scratch the die. Essy to get depth measurements from breech face to the die, then lock it on the threads with the die adjustment screw.
