I think lining is only available in .22's (I could be wrong). Have you removed the rust? If it is pitted, you can live with it or replase the barrel.
Shoot it and if it groups within three MOA don't bother replacing it.
I have heard of barrels being bored out and an liner installed. On a centerfire highpower rifle, I don't think that is a good solution as the liner is going to move.
Barrel replacement is the cheapest option and you have to examine the costs to see if your rifle is worth the price of the replacement.
Is your Mauser all original military or has it been sporterized?

Im looking at barrel replacement costs now.
Some backstory. When i first got the gun, i ran a cloth through the barrell to get any dust or dirt out, but i didnt use a copper bore guide cleaner. I shot the gun, WITHOUT a scope on it and i was hitting 3-5 moa at 100 yards with the factory sites.
SO, i get it home and i clean the gun. I use the copper bore cleaner and put some Krohl in there. Let it soak, cleaned it out. Thats when i saw all the rust and what not. I then added a scope to it. Took it to the range, and i couldnt seem to stay within 1 foot. I would shoot it once, then the second shot would be 12"s left or 12"s right. It was just sparatic. Scope appears to be tite, but its one of those mounts that clamp around the barrel.
Scope? Im going to take it out again and see what i can do. Im shooting Yugo ammo.

Take the scope off and shoot irons @ 50 or 100 yds. That should give you a little better idea how bad the barrel is. Is this barrel full length or has it been chopped?

It was shooting 3 to 5" @ 100 w/o the scope and 24" w/ the scope. I would figure the rifle out before I spent money on re-barreling.
Ya, it was 5 inches or so.. It could of been a bit more then 5"s but it was all within the black. I think it may be the scope mount. Im going to take the scope off and try that at 50 like recommended.
One thing i didnt mention. When i cleaned the gun and put on the scope, i also changed the stock on it also.

I don't think it's as easy as screwing one off and screwing the other one on. I'm pretty sure the chamber has to be (at least) finished reamed.
This is a tough one. My gun is a 1945 spanish. I believe its a m43. Some say identical to a 98k. So would this barrel fit this gun.

Before you go to all that trouble & expense to ruin another mil-spec rifle, why not clean the crap out of it with JB Bore-Paste.

You might be surprised what a real good cleaning will do for it.

Question on the JB Bore Paste: I've only used it a couple of times, but each time I noticed the patch comes out black as coal; it didn't seem to matter how many times I repeated the process. Very small amount of Grey paste goes in, nasty BLACK junk comes out. Is there ever a point where that stops or does it always come out black? I tried it w/ both solvent and clp.
That black junk is fouling. I use a tight fitting brush with a patch wrapped around it, and run it through the bore 30 to 40 times, changing the patch as needed. Then I clean in the regualr way, solvent and patches untill they come out clean. Kroil oil is great to use with the JB bore paste. It may improve rhings for you.
JOhn, I did that... I didnt do it 30 or 40 times, but i did it a few times. And actually now that i think about it, i could never get the rag to come out clean. I was just thinking that was just the color of the barrel and it wasnt supposed to come out perfect....
I will try a better clean job, remount the scope, remove the aftermarket stock and reinstall it a bit more carefully, paying more attention to clearances and give that a shot.

Will it ever come out 'not Dark Black'?
The last time I used it, I worked on it for a couple of hours. Way more than 40 passes, changing patches and wipping the bore out with solvent or oil between patches My arm hadn't been that sore since I was 15! The last patch came out just as black as the first.

Black patchs indicate the barrel is not clean yet.
Gray patch indicates the JB is starting to polish clean steel.

JB Bore Paste will come out black in a perfectly clean barrel.
The black is caused by the fine abrasive polishing the metal, which causes the paste to turn black.
Read the directions on the jar and don't over use it.

AFAIK, there are no new 8mm military contour barrels available; the only 8mm I see in Brownells is an unturned blank. An 8mm barrel from GPC or anyone else will be a take off, with all the possible problems that entails for headspace, sight position, etc.
No, lining a high power rifle barrel is not possible. Where there is a need to preserve the markings of the original barrel, the barrel can be drilled out to a hollow shell and a new barrel turned down and inserted into the shell, but the inner barrel can't be just a liner - it has to be thick enough to contain the pressure all by itself.
To those who complain that the patch keeps coming out black, I can only ask where you think that black is coming from. That is the dirt you want to get out. Keep scrubbing!
