Does anyone know where I can get a new barrel for this gun???? My dad has this gun and every time he shoots a round, the extractor grabs the casing, and rips part of the back of it off. We then need to send a pushrod through the barrel to knock out the casing. It is as if the chamber has expanded or shrunk, and the shell casing has expanded, which explains possibly why it gets stuck. To answer any questions that might come up, we have SUPER cleaned the gun, and can not see a single filing or anything in the chamber that might be holding onto the casing. I have looked everywhere online and can not find a barrel. The couple of places that i have found them for sale say that they are out of stock and can't get any more. To top it off, Remington won't give us a quote on a new barrel and gunsmithing costs. Any help would be greatly appreciated!!!

You don't need a new barrel, I have been repairing this problem on Rem auto rifles for many years. Take it to a competent gunsmith who will remove the barrel and polish the chamber--solves the problem every time. The chamber of those rifles is somewhat difficult to clean properly and it gets a layer of super fine rust which causes the expanded case to stick for a microsecond, just long enough for the action which is gas actuated to move and the rim rips off. You're lucky, sometimes on the 742 the edge of the bolt rips off and you're SOL. Here endeth the lesson. Goatwhiskers the Elder
I have another theory on this too as our department purchased one in .30-06 some years back for dealing up close with furry and ugly.
I noticed that the same thing would happen when we used heavy bullet loads of 180grs or more. Yet the problem didn't show with lighter bullet loads.
I cleaned and inspected the chamber as bet I could but could not see anything obviously amiss.
My theory is that the longer pressure curve with the heavy bullets using slower powders are the real culprit which disappears when you drop down to 150s with faster burning powders with shorter pressure curves and allows the case relax faster because the pressure drops off faster.
Of course I could be wrong.

Stevelyn, I'd say that your theory could be true, except that we have sent every single type of basic brands and loads, that can be bought at a typical outdoors store, through that gun. Unlike me, that gun doesn't discriminate, LOL. Same problem with every shell. Very occasionally, one won't hang up. But this has no set pattern to it. More than likely, the shell hangs up. Thanks for the thought though!

Tell ya what, when you get the rifle repaired, cut a length of coathanger wire that suits you, bend an off set in it, and make a loop in the end to hold a patch. Whenever the gun is put away, swab the chamber with an oily patch. Now remember to always when the gun comes out for hunting to swab thoroughly with a dry patch, the engineering of the gun requires a dry chamber, a wet chamber results in more violent working of the action, consequently rapid wear. Remington used to sell a lovely little offset chamber brush, but no more. Cheers, Goatwhiskers
If you post on the classified sections of a few gun forums you should be able to find a brand new barrel for around $25-$50. Lots of guys buy new rifles to use as customs and will often sell the take off barrels for next to nothing just to get rid of them. A gunsmith who does custom owrk probably has a few laying around for the same reason.
If you have to go to the expense of removing a barrel and putting it back on in order to get this one fixed I'd just as soon spend a bit more to get a new barrel. Might even take this opportunity to go ahead and have a full custom barrel from one of the custom barrel makers such as Lija, Hart, or Douglas put on at the same time.
