    Default Is it possible? 7.62x25 Mauser

    I have made a few rifles at school (Trindad State Junior College) such as .308, 30-06 and a 25-06 all on Argentine 1910 mauser actions,,,a friend at work wanted to know if it was possible to make a rifle using a mauser action and chamber it for the 7.62x25 cartridge,,,I told him I did not know and had never given it any thought. could this be done maybe using a mauser short action,,,I wonder if the 7.62x25 cartridge would have enough velocity to exit a long barrel,,,just wondering,,,SEMPER FI

    There is a thread right now on the fal files where a guy is building a 7.62X25 AR, and he is even keeping it gas operated. So yes, it will exit a longer barrel.

    I have seen a Lee-enfield converted to 7.62 x 25 Tokarev,probably easier to go thet route.

    Probably could be done, but not worth all the effort that it would entail IMHO. Much better would be to start with a Spanish Destroyer Carbine with poor barrel or that Bubba has already gotten hold of. Mags, bolt face should work with little or no alteration, plus could be made lighter and handier than anything built on even a short Mauser action. That would make a dandy "walking around" rifle.

    it could be done & would make a neat little plinker. the best & easiest way i could see to do it would be to bush the bolt face to the correct size then cut the bolt for a sako style .223 extractor. position it so its under the orginal extractor when the bolt is closed.leave the original extractor in place just grind off the front of it. if you ever split a casehead the original extractor will prevent the sako extractor from flying out the side of the receiver.
    figure out what type of magazine your going to use & make a magwell adaptor for it. you could also move the bolt stop forward about 1 1/4". to shorten the stroke wen cycling the action.
    i've always wanted to shorten a 98 by about 1 1/2" & chamber it in 45auto.

    I wish someone would make a barrel for those cheap "tip up" single action rifles in 7.62x25mm. Or all the tip up single shot shotguns around (same thing?) It Would make a nice cheap plinker!

    I have an old 20ga. single shot in the gun room....any one want to fit a 7.62x25mm liner in there? Should be loads of meat in the chamber area to mount a sight or scope mount!

    Ed Harris over at the Cast Bullet Association web board has a rather lengthy experiment doing just that. He started with a .410 Single shot Beretta and had several new barrels made that drop right in. The calibers he's experimenting with are .357/.38 Special, .32 S&W, .32 H&RM .45ACP, and a few others. I seem to recall he told me his cost per barrel set was about $75 to $100 each.

    I shot the .45ACP conversion quite a bit last time we went to the range. With the long barrel he's using, the sound level is such that hearing protection is optional. Very accurate out to 100 yards or so. We were pinging a steel silhouette out at 100 yards with head shots and open sights.

    Pretty neat little rig. I am sure a 7.62x25 conversion would be easy peasy.

    He calls the project his "bunny gun" project. You can do a search for the word "bunny" and see all his threads on the project.

    Here is one post with good photos showing the results of his work with the bunny guns:

    your on to something there i have two old h&a dropping block shotguns one in 16 ga. & one in 20 ga. in the 16 ga. i made an 32-20 insert from an 09 arg. barrel and for the 20 ga. i made a insert in 25-20 from an gov. cut up sav. 23 barrel and to make things more fun i took some 25-20 & 32-20 brass and bored out the primer pocket for a 209 shotgun primer load up a round with just the primer with a round ball and you got a poor boy big bore bb cap

    The rifle receivers are built different from the shotgun receivers in terms of material and heat treat. For a .30-30 or thereabouts, the shotgun receivers work just fine. You get into "interesting" territory with rimless shells in the tipup guns. So long as you can use a rimmed shell, they run fine.

    Since these run so much better on a rimmed cartridge, I have been forming .38 Special into a rimmed 7.62x39, and leaving the neck long. It is a cast bullet cartridge from the upper reaches of the river....

    Default 7.62x25

    Yes it is possible, When did you go to TSJC? I was their from 91-93 myself. I have one of the rhineland arms 45acp conversions for the mauser rifle and it is a very fun rifle to shoot.

    I have built a 7.62x25mm on a 1903 Turkish Mauser [Orberndorf].

    I have also built a 223 on a 1903.

    I am not doing either any more.
    I hate the extractor work.

    I got a Rem721 30-06 barrel off Ebay and cut down the breech, threaded and chambered it.

    At that time the 30 Mauser reamer was much cheaper, and had the same dimensions.

    With S&B factory ammo, the best I did was 1.2" 3 shot group at 100 yards.
    I think I could do better with 110 gr handloads, if I ever took it back to the range.

    Another alternative is to do what the Chinese did--they converted M1 carbines to 7.62X25 as well as Japanese bolt guns. I have examples of both. The carbine came without a magazine but I was able to make one by pop riveting a hobby shop brass square section piece on to the magazine spine to better align the cartridges in the magazine.

    I found, in a gunshow junk box, some 1911 barrels converted to 7.62x25 by swaging in 30 cal barrels.

    I posted that on line, and some guy was willing to pay anything to get them.
    He thought they had some Chinese historical significance.
    He has them now

    I am said "goofball". I obtained thru many years of patience and stoke of luck a Springfield 1911 converted by unknown, although likely Chinese, means. The advent of the recent Yugo M57 Tokarev pistols has given me a slew of magazines to experiment with...

    I did want Clark's barrels to put with the pistol and to see if any of the conversion work was shared. And Clark didn't rake me too hard over the coals.

    If you are him, no one is likely to call you "goofball" to your face. That guy looked like Brock Samson, the Swedish murder machine.
