Thread: Ortgies 32acp barrel bulge.

  1. #1

    Ortgies 32acp barrel bulge.

    I resently aquired an old German ortgies 32acp that was locked up in the open position. I have enclosed a picture of the barrel. Any ideas on repair?

    Easiest would be to see if Numrich/Gunparts corp or another has a replacement barrel, or it would be possible to build a tool with rollers to physically iron out the bulge, assuming of course there are no splits in the bulged area. I heard of a fellow who was a machinist, and simply turned the bulge off on a 1911 barrel just to try it. He claimed it shot just the same as before.

    Try taking the cutting blade out of a good set of tubing cutters and roll and squeeze carefully. It might help to drive a long .30 cal cast bullet down the barrel for support. Just a thought.

    Gun parts is out of the 32ACP barrel but they do have a 25. I have seen a few guns that shoot OK with a bulge, you could turn the barrel down over this area. Or have a new barrel made.

    I know a guy who used an anvil and ball peen hammer to fix a bulge. Darned thing shot just as good as it ever did.
    The solid soft lead bullet is undoubtably the best and most satisfactory expanding bullet that has ever been designed. It invariably mushrooms perfectly, and never breaks up. With the metal base that is essential for velocities of 2000 f.s. and upwards to protect the naked base, these metal-based soft lead bullets are splendid.

    Forget everything you know about loading jacketed bullets. This is a whole new ball game!

    I was wondering if a gunsmith might cut off the old barrel about flush with the chamber. Then drill and tap .500x28ef seating new barrel at the end of the firing chamber.

    Not a bad idea. I wonder if squeezing that displaced metal back down would make the barrel longer? Not saying it wouldn't work, just curious if it would lengthen the assembly.

    Some Browning Hi-Powers had two piece barrels that had the barrel tube silver soldered into the breach section. It was cheaper to build them that way and they held up just fine. Maybe the barrel could be cut off of this one and the breach section reamed out to accept a new barrel with a reduced shank on the breach end? Not sure if it would work but not much to lose at this point.

    There is a barrel on gunbroker. I would get it as backup to one of these solutions. If you get the original barrel shooting well, just resell it.

    I have replaced bad barrels on several pistols by cutting off the barrel , then machining it out to fit a replacement barrel with the shank of the new barrel turned down slightly. ( no need for threading )
    Old Lugers were done that way when you couldn't find barrels.The barrels were simply silver soldered into the original Barrel Boss and then rechambered.
    And if there was enough meet on the barrel and boss, a cross pin can be added.
    But if you make a Mandral to fit the inside of the barrel, and you place it in a lathe, the bulge could be Rolled out.
    But the strength of the barrel may be in question after it is done, But if you do a chamber or full barrel cast afterwords, you can see if the rifling is effected.

    Might want to check the OD of a piece of .32-20 barrel liner, you may be able to use the old barrel for a monobloc and just sleeve it. Or do a stub refit with a turned down piece of .303 or .30 cal. rifle barrel. I have a 10-inch twist .32 ACP done with a chunk of .30 cal. rifle barrel which shoots wonderfully and is more accurate than was the original pistol.

    If you don't have a .32 ACP reamer you can use the front of a .30 M1 carbine reamer stopped short.

    are you making barrels in 9mm Luger for these guns?

    Thank you

    O.P. I just happen to own one of those old Ortgies .32acp's.
    It is not in the best of shape overall, but the barrel is in great shape.
    Grips are cracked/broken, I can't even remember without digging it out.
    One magazine.

    Give me a pm if interested.
    I don't want much for it.

    Many years back , i came across a bunch of Astra 9mm Largos for dirt cheap in almost new condition.
    I converted them to 9 mm Luger by making a spacer to fit the front of the chamber, then reamed the chamber to 9x19
    Most of the inserts were simply pressed into the front of the chamber with a press fit.
    Others I did by sweat soldering in place.
    The press fit seemed to hold up just as wall as the soldered ones.
    IMO, there is no need to get a New Barrel to convert 9mm Largo to 9x19
