    New to this thread. I have an old Mauser carbine that I bought probably 40 years ago. I have kept it cleaned and oiled, so it can be fired. I have taken it out to shoot several times in the past, and found that even with a sandbag rest, the gun shoots inconsistantly,and very inaccurately. I've spoken with others over the years, and was told the barrel was " burnt out ". Is this possible?
    All the numbers on the gun match,so I'm a little unsure of changing out the barrel. Does the gun have any value other than as a shooter,so that a barrel chenge would not make any difference in it's value?
    Is a barrel change something that could be done at home,or do I want to take it to a gunsmith?
    Are there any places where the barrel would be available? I haven't seen any on line,so I'm at a loss here.
    Would I be better off just hanging it on a wall?
    Any advice,comments,etc. would be appreciated. thanks

    Before making any changes, what ammunition are you shooting? Surplus ammo can be very inconsistent. Try some commercial manufacture ammo before going the barrel replacement route.

    It would also be helpful if you would give us more information on the rifle itself. If you'd post some pictures, that would also be very helpful. See if you can get us a good shot of the bore and crown.

    there could be many many reasons that it don't shoot well. We can not tell you if a barrel change would hurt the value without more info and good pictures. Basically the answer is no to changing the barrel yourself and buying a barrel and having it installed would cost what the gun is maybe worth. If you want a project we can give you many relatively low-cost things to try to get it to shoot better. My first impulse is to say sell or trade it for a commercial made rifle(non-military) or just hang it on the wall.

    Commercial 7 X 57 Mauser ammo is loaded to be compatable with even the old '93 Mausers and will be safe to shoot in the rifle you own. Get some of that first and see how it shoots. Guns like you mention are only $150-$200 guns even in good shape. While rebarreling is possible, the cost of doing so will far exceed the value of the gun. I also have an old 7mm Mauser that I bought 40+ years ago for less than $20.

    I have a place where all they deal with is Mausers. It's called Mitchell's Mausers out of Fountain Valley,California ( Mauser.net ). They should answer all your Mauser and Mauser ammo questions.

    It depends on what you consider innaccurate. That is a service rifle, not a match rifle. I have two Spanish "short rifles" in 7X57. They shoot MOA (Minute Of Azzhole) at 100 yds. They do not shoot 1 1/2" groups. They probably never did.

    Is the barrel worn out? Maybe. Clean VERY thoroughly using a copper solvent like Shooter's Choice or Sweet's 7.62. They will help you get the century old gunk out.

    Mitchell's is not looked upon very favorably by Mauser collectors. I will leave it at that.

    The 7x57 is one of the most accurate and deadly rounds I have ever
    shot. It is absolutely lethal on hogs. You might try plugging the barrel,
    then fill it with Kroil, let soak for 24 hours, then clean normally. Though
    underpowered, Remington 140gr core-lokt does a good job.

    +1. In the Boer war the Brits were outranged by 7x57 Mausers. Examples were brought to Britian and the U.S. Both had plans to build a clone. The U.S. did copy the '98 action w/ the 1903 and lost in court to patent infringment. Paid a license fee untill the breakout of WWI. The M1 garand was supposed to be chambered in .276 Pederson, untill MacArthur got involved. It would have been a 10 shot semi. The .276 is a clone of the 7x57, as the .30-06 is a clone of 8x57.

    we bought an old spanish mauser a few years ago. it shot horrible. bullets were key holeing even at 50 yds. we lightly cleaned the bore and it looked clean but still wouldn't shoot for crap. we scrubbed the crap out of the barrel and chopped it to 20 inches and recrowned it. still not a tack driver but now maybe 3 inches at 100 yds. no more key holes

    Mil-surplus rifles were never mint to be 1000 yard bench rest rifles that can shoot ½ inch MOA half way across America. The ability of a Mil-surplus rifle is to kill solders and they meet these criteria hands down.

    Accuracy of 3 inches at 100 yards is expectable for old Mil-surplus rifles, if you got one that shoots tighter groups then hang on to it. I get around 2.5 inch groups at 100 yards with my MN 91/30 using Iron sights. This is will within the excepted accuracy range that the weapon was made to do.

    Also remember that the ammo for most Mil-surplus rifles was mass-produced and quality control was mostly making sure that each box had the right amount in it. If you want a tad bit more accuracy then look at shooting some good factory loads from one of the major manufactures in the U.S. or reload your own

    Scoping it may improve the accuracy some but I don’t think you will get sub-MOA’s out of it.

    Have a few 7mm military mauser rifles and while hardly match rifles, they'd be just fine for deer hunting. Actually, a couple of my 7mms shoot pretty darn good for a military rifle. As suggested, I'd give the barrel another good cleaning and probably do a crown job on the muzzle before replacing the barrel. I've improved the accuracy of a number of mausers or other military surplus rifles just with a crown job, something you can do yourself. Just something as simple as a carriage bolt or a large brass screw using valve grinding compound on the head of the bolt or screw and using it in a drill to lap the end of the bore may be sufficient to correct a damaged crown.

    By the way, you can buy a sporter replacement barrel from Midway for around $80 that is prethreaded for a mauser action and short chambered. There are a number of cartridges you can choose from, including the 7x57 mauser. Since they are short chambered, someone will need to run a finishing chamber reamer into it to set the proper headspace when installing the barrel.....a relatively simple task, but recommend using a gunsmith to do this since he will have the expertise and tools to replace a barrel. Now if you want a new replacement military contour barrel, they can be found, Walter Lothar barrel company makes one and Cole distributing still has some new Norwegian 98 mauser barrels, but they are threaded for only large ring mausers and available only in 7.62x51 (308Nato)
