Default Straightening rifle barrel.

So I got a deal from my neighbor on a savage 99 takedown in 300 savage. The reason for the deal is obvious... ImageUploadedByFirearms Talk1408225329.931472.jpg
Anyways replacement barrels for this old rifle are not available that I could see. I decided to try straighten it out so I first tried using a jack vs the diff of a truck but that only helped a bit. brought it to my brothers work and used a press and it is perfect now! ImageUploadedByFirearms Talk1408225437.455442.jpg

Excited to put it together and give it a whirl

you really need to slug it first. a bend that bad may have left the bore pinched. send a round through it with a constricted bore and you have what is called a pipe bomb not a rifle.

once you have slugged it measure the slug and lok for out of round condition along with anything that looks like its been gouged. if its constructed the slug will be less than the diameter of the bore originally. anything less than .300 and its probably constricted too much to be safe. barrel steel is very similar to glass in how it behaves in that it tends to crack and shatter. evidence of that will be like if something was ripping at the slug as it went down the bore.

personally i wouldnt wantt o be behind that when it goes off. metal stressed that much is going to be weak as hell and will kaboom at some point.

Post a range report when you do. I'm curious as to how well the pressing worked out. Got a friend with a bent barrel on his NEF Pardner, (mild bend, but a major PITA when using slugs) that I wall pass this idea on to.

Many gunsmiths can fix you up with a new barrel. I'd cough up the bucks for that before I would trust my life to a barrel that has been bent, then straightened with a hydraulic press.

Slug it though, at a minimum before you take steps that involve actually firing a round through it. If it were me, I'd tie a string to the trigger and be at least fifteen feet away when I test-fired it. Then I'd take a good look at the brass to look for pressure signs.

Over-all, your best bet is to take it to a good gunsmith, tell him the whole story, and then do exactly as he suggests.

Good call. Just pound a soft piece of lead through?

The radius of that bend probably wouldn't lead to any problems. I would
Use the old string and tree stump method to remotely trigger a few roun
ds and let it rip. Then again, I am old, and don't have a lot to lose.

yup like a fishing weight just barely bigger than the bore. grease the bore and the lead well before forcing it down the tube.

use a dowel rod cut in sections about 3-4 inches long to do the pounding. drop from the breach end then out the muzzle. after you do that and it all checks ok clean the grease tie it to a string get behind cover and test a bunch of rounds.

i still wouldnt fire it. bending barrels to shoot around corners like the germans did was a pure desperation move. the initial bend isnt really the bad part its the bending it back. your work hardening the steel which makes it more brittle and less able to stand pressure which is why it may not be safe to fire.

you get the same effect by taking a piece of wire and bending it back and forth in the same spot it eventually snaps each bend stress the metal than the last. its a cumalative thing.

I agree with Jon on this one, you did a fine job on straitening it but the area it bent at is now much more prone to doing very bad things like blowing up, the metal is not the same strength once you stretch it. Even if it Slug tests fine, its not safe, no way. Its just an accident looking for a place to happen, I really think chopping it up for scrap is about the safest thing you could do with it.
