Rifle in 7,62x25

A single shot break action would be easy to clean and cheap to produce.

Yep! Affordable and would do what I want with it. I’d buy one in a second!

You got me thinking about my Thompson Center Contender now.... I wonder if I could get a 7.62X25 barrel for it. Or even a blank .308 barrel and have it bored out. Hmmm.

I saw something today that's cheaper and easier for those with bolt action 7.62x39 owners. A long time acquaintance dropped by today with some lovely stainless steel inserts he had made for his Zastava. He got the idea from the Hammond game getter and an old Sportowy Russian 22rf semi auto pistol he has.

He made up half a dozen chamber inserts that are profiled to the 7.62x39 on the exterior surface and chambered to the 7.62x25. To easy and also cheap. His work was good and his groups would take grouse and rabbits out to 50 yards IMHO. Now, I need to find a used reamer.

I have no excuse for not thinking of this myself. I have inserts to use 32acp cartridges in 303Brit and 30-06 and another to use 45 colt in my 577/450. Why I didn't make the connection?????
 
Seed planted...
TT33 uses 1:9.45 twist. Any issues with slinging out of a 1:12 barrel?


He just showed me his rifle/inserts/target. He was shooting into 2 inches at 50 yards. That's impressive considering how much freebore there is with that system. I didn't get the chance to measure the bore on the insert he showed me but I'm willing to bet it's very tight.

He used stainless because he feels there will be less expansion of the insert. I don't think it will be a problem but there isn't a lot of steel left after the chamber is cut into it. He's a very bright fellow and a good machinist. I wish we lived closer. Now we only see each other once or twice a year.

I think a Thomson center fire would be great...and the easiest to do.
 
daft moment...longer twist shouldn't hurt smaller bullet. It's going heavier with a bullet bullet that requires shorter twist.

This is true but it also offers the possibility of loading the little cartridge with heavier bullets such as the 123 grain or 100 or 110 brain offerings.

My consideration for barrel twist is almost always heavier, and faster... Speed and weight being factors. I don't think a common 1:12, .308 bored rifle will be too slow a twist for the surplus x25 ammo. The only reason I would build something like this is for:
1: kicks
2: surplus ammo rivaling rimfire cost
3: reloads possible

For me, this build would start with a barrel.

The added velocity of a longer rifle barrel would likely equate to a similar bullet rpm as produced by the pistol. It might even be necessary to have a slower twist so that the bullet doesn't over-rotate and shed it's jacket. There is a lot of potential for velocity if that whole Tokarev muzzle-flash is actually contained and used to propel the bullet from a longer barrel....
 
There was much discussion on this a ways back.
I was forwarding the idea of an M1 Carbine looking clone to shoot the 7.62x25 Tokarev Pistol Cart reliably.
Not an exact clone obviously (ditch the rotating bolt system of the M1/M14 system) but something simple, robust and reliable. Make it a delayed blowback, tilting block action. Something really simple.
Make it take TT33 mags to boot and we can all see the advantage of that :D
Or we could manufacture cheap TT33 mags in Canada for the "TT33 Pistol" that hold a full 10 rounds vice 8......

Fack it would be a cool little carbine! I would have to consider getting back into the crusty corrosive bullet hose game again if a rifle was to materialize!

So it's settled then....

I demand CZ make a single shot conversion insert for my CZ527 in 7.62x39 to shoot 7.62x25. Ooh that would be sweet....
 
Wonderful device! Thanks for showing that to us. Why can't stuff like that succeed!!??

They made thousands of them. They destroyed most of them before they were issued. Some seem to have escaped the destruction. Back in the seventies I saw one of those in Ed Karrer's Gunatorium. He actually had a couple of them installed in mint 1903 MkI rifles hanging on the wall behind the customer counter. I loved that shop. It was like Lever Arms on Steroids. Besides the two in rifles there was another two under the counter that you could get a close look at. I offered to purchase one of them but there was no way Ed would part with them. It seems he managed to get them from a National Guardsman in a trade. He also had a case of ammunition and spare magazines. I wonder if the device in the video was one of those???

IMHO the reason they were destroyed was to promote the development of sub machine guns. If those were left available the Army/Marines would make do.

They didn't survive the transition from prototypes to mass production very well. Field trials didn't actually happen until the first mass production units arrived in France and they were... Terrible. Horribly unreliable.

It's a tremendous concept, but it was rushed into production too fast. The factories hadn't worked out the kinks before they went into mass production.

The trouble now is... What bolt rifle is mass produced enough, and in common enough use, to make it commercially viable again? Pretty much none. A Mosin conversion for x25 would probable be the best bet, massive numbers of them floating around, and large amounts of surplus x25, but would you be able to sell enough of them to get the price to a point where people would actually buy them? Probably not.

Still nice ton dream the dream, though.
