7.62x39 Conversion

At the same time as the .223 Remington conversions, another caliber conversion also appeared. 7.62x39mm. I experimented with a 7.62x39mm conversion before I started on a .223 conversion, but later sold the rifle and ammunition.

The 7.62x39 conversion is a little cheaper, because the original .303 barrel is recycled. The bore diameter is perfect for surplus Com-Block ammo. There are two methods of chambering. The first is to cut off the original threads and then machine new threads onto the barrel. The headspacing is more than good enough. If you look at the shoulder/neck areas of a 7.62x39mm and a .303 British, they are almost identical. The second chambering method is to cut more than the threads, like 5mm (or about .2") more and then use the appropriate reamer to cut a new chamber from the metal. The collar on the bolt head is similar to the .223 Remington, but narrower because of the wider base. For magazines there are two possibilities. The first is to modify an AK-type magazine to fit the Lee-Enfield's magazine well. Some gunsmiths managed to alter the receiver to take an unaltered magazine. The magazines were typically shortened to a more convenient length (typically 10, 12, 15, or 20 rounds). The second is an insert, again similar to the new design .223 Remington conversion magazine, but altered to fit the dimensions of the 7.62x39mm.

.223 Remington and 7.62x39mm are well within the limits of the No4 receiver and don't have to be proof tested.

Yah the price of .303 is killing me, even with reloading.
I was thinking of a bolt action companion for my SKS.

Hehehe, I didn't think about AK mags. :D

Also jjwelin, keep us posted on your project. :)

"...bore diameter is perfect..." Not necessarily. An Enfield barrel can measure between .311" and .315" and still be considered ok. Slug the bore first.
You'd have to make a chamber insert to get the 7.62 x 39 to work. It'd have to be headspaced for the much shorter cartridge.
 
Enfield "K" in 7.62x39!
By Special Interest Arms.

The classic #4 & #5 Enfield's have been updated to shoot the inexpensive and accurate 7.62x39 cartridge!

The converted gun uses interchangeable 5 and 10 round single stack AK-47 detachable magazines!

No modifications to the original Enfield receiver are required.

"K" for Kurtz *, the 7.62x39 round uses the same .311 diameter bullet as the original .303 British caliber, but with a lighter 125 gr. bullet, in a shorter cartridge case.

Ideal for youth, ladies and anyone else desiring a .30 cal. rifle with light recoil!

Inexpensive to shoot, plinking ammunition is typically only about $3-$5 a box!

Soft point hunting ammunition is readily available!

Reliable bolt action design, conserves on ammunition cost and promotes accuracy!

All Enfield #4 rifle accessories remain fully compatible with the new Enfield "K"!

The bolt action and heavier barrel appear to greatly enhance accuracy over that to be expected from SKS or AK-47 type rifles!

Did a No 4 in one of our gunsmith classes last year. Used the Chinese bolt action single stack mag for the conversion. Used the origional barrel, works well and shoots pretty good. Funny, the recoil seems quite stout for this rifle, managable but more that I expected.

Hmmm, interesting, maybe the semi action eats up a lot of the recoil...
 
No... I have a ruger M77 mkII in 7.62x39 and it is a pussy cat to shoot and it weights less than a #4, might even be less than a #5.

Take "Sunrays" advise and slug your barrel. Many .303's went through my hands and some measured up to .317 " and with a good looking bore !
Go figure ....Tooling ,I guess.....
 
I was going to do this, still may. Right now I just pull the bullets on X39 and reuse the bullet and powder in a 303 case. Works great, with no gunsmithing.

Now that is an interesting idea! Is the powder charge suitable for just dumping into the .303 case, safe pressures etc?

Yes, I just dump the pwder from the X39 into the 303. About 23 grains. It is low pressure with a bit of sooting on the case, but it still seals fine. I imagine the cases would lat a long time, too.
