bend in barrel

    Just got a Remington model 591 5mm. I want to convert the bolt to centerfire. I purchased this rifle online, when i got it today first thing i did was look down the bore. Its bent!

    Is this something a gunsmith can straighten? Or would i be better off haveing a different barrel threaded on it? I guess ive just learned the expensive lesson of purchaseing a firearm you dont inspect first. But if that barrel is junk, the action is still fine. I could just put another 5mm barrel on it, or a .19 calhoon hornet barrel on.

    Any advice on this? Any other ideas of what else i could do with the old M.591?

    Is it just the bore not being straight ? How does it shoot ? If the bore isn't straight and it shoots poorly then replace the barrel. Straightening a bent barrel isn't a ggod idea as it likes to return as it warms up.

    "I want to convert the bolt to centerfire."

    I confess I am not familiar with the Calhoon Hornet, but the standard Hornet is way too long and too fat to fit the magazine; the bolt face would also have to be altered. Also, that action, even though not a bad one, is basically a .22 action and might not be up to the higher pressures of a CF cartridge, even one of the Hornet type.

    I can't tell you what to do, but IMHO the gun is not worth working over; a new barrel alone would cost more than the gun is worth, not to mention the gunsmithing involved. It might be an interesting project, but probably a costly and frustrating one.

    thanks guys. To answer your questions, yes the barrel is bent. I can see all the way down it, but i can only see half of the hole at the end. It is bent downward. Ive been afraid to shoot it out of safety reasons.

    The bolts on the rem 591's and 592's are 6 lugs. They are designed for way more pressure than the 5mm could ever produce. Several have been rebarreled for the .19 calhoon. It is possible.

    I think maybe my best bet would be to find another 591 and use the 2 to make the best rifle for a centerfire conversion. The stock and action on this one are in great shape. All i need to do is find one with a good barrel. They are not to expensive since they are useless unless you want to alter one. $100-$150 should find me one with a good barrel. Then ill do the .19 Calhoon, or .19 Badger project another time.

    Should i try shooting it even tho its bent?

    Thanks Again!

    You could always keep it as is for your own "Maschinenpistole 44 mit Krummlauf" wannabe and bend it just a little further.................you'd just need 30 degrees and you'd have a M591 mit Vorsatz J............add a mirror sight..........:neener:

    lol, just incase i need to shoot something under 50 lbs around a corner, or out of a tank. The only problem is that it bends down.

    Here's a real good chance to have a bit of practice at barrel straightening.

    Just go outdoors, find a nice straight corner of a building to use as a reflective shadow in the bore and a solid fence post .

    Strip the rifle to barrel and action body, find the high point of the bend and bash the top of the post with said high point.

    Look through the barrel at the afore-found straight line and keep bashing until you got a straight reflection.

    Alternately use the reflection of the muzzle, which appears as circles in the bore; where the bend is they will not be concentric. Bash until they all are concentric.

    First bash should be fairly heavy, reducing as the barrel straightens.

    Straightened barrels are safe to fire and they are often straightened in the factory during manufacture.

    It was a common military Armourers' practice when a rifle couldn't be zeroed because it was beyond the range of foresights and the cause was not a bent barrel, to bend the barrel slightly to be able to zero it.
