Anyone rechamber a Mauser?


January 31, 2007, 06:43 PM
I've pondered rechambering my Yugo M48 to 30-06? Anyone know what this involves or what it might cost? Do I need a new barrel? It is better to start with a whole gun, or just an action and bolt? I don't need a super accurate rifle, but it should shoot as well as it does now.

Thanks in advance -

To convert a Yugo M48 to 30-06 you will need to:

Remove the old barrel
Install a 30 caliber barrel
Chamber the new barrel
Lengthen the magazine box to accomodate the longer round

This is a very basic outline of the steps involved. There are many details that I've glossed over such as correct headspace, stock inletting, etc.

If you are trying to sporterize the rifle, you will probably want to have the bolt handle bent, a different safety installed, install a scope mount or iron sights, and get a new stock fitted/bedded.

Ya might have a problem with the M48 Yugo being a lil shorter than a standard 98 mauser, its considered an intermediate length action. I'm not home at the moment so can't check the actual length but the 30/06 is 6 mm longer than a 8x57...

Try e-mailing Pac Nor or any of the other barrel makers for a price on the barrels to start. I know Pac Nor also installs and is spoken highly of as a good company for both barrels and work. All you should need is a barrel installed. The smith whom does the work should include chambering and setting of the headspace as part of the job. Action trueing may be wanted but isn`t a must. Barrels can be had to fit the stock channel and in some cases may be a std offering. I would expect to have the stock channel opened up a bit to recieve the new barrels shape. The action should work fine with a `06 if it was a 8mm to begin with.
I have rebarreled 5 rifles over the past 15 or so years, and prices have ran from ~$350 - $600 depending on who did the work and the barrel used.

what dstorm1911 says rings true to me.

I suggest doing the next best thing...if you MUST rechamber a mauser, and its that intermediate action length, do it with a 308.

You still get a 30 caliber, and the ammo is as plentiful.

I would go with a Hart barrel personally (Thats what I have on my Brno) but you can get a Adams and Bennet barrel off Ebay fairly cheap.

Just so happened I ran into a local gunsmith in one of my favorite shops on my way home from work today and he was looking for a mauser action so he could rechamber for 7.62x39. He was thinking of just buying one of the Turkish 8mm mausers for the conversions.

Another issue when rebarreling an M48, these had the fully enclosed case head feature which is absent on the typical Mauser 98. This means that a new barrel will have to have a slot milled for extractor clearance or the extractor will have to be modified.

old thread but worth replying to- on the issue of rechambering to 7.62 x 39- I've thought about having that done on a Mauser rifle as well, but then came to the conclusion it would be a waste of a good M98 German Mauser action. The M98/K98 is well known for its strength and ease of putting a barrel on it. It just doesn't make much sense to use such a dimunitive lower powered round to rechamber it to. After giving it a little thought, if it was going to be rechambered to anything, it should at least be one of the original 55mm or 57mm length cases i.e. 6-6.5-7-7.65-8-9 mm's, or the later 30-06 length family i.e. 270 280 '06 35 Whelen, or the 250 or 300 Savages, or 243/308/358 Winchester family, or 260 Remington.

rechambering to a 7.62 x 39 may sound like a cheap way to shoot a lot of berdan primed milsurp ammo, but the round is barely as powerful as a 30-30, and actually less powerful than a 30-30 with the heavier bullets. Just seems like a waste of a really good action. and that milsurp is mostly low quality and FMJ bullets, and throwaway brass.

the 1908 Brazilian I just acquired, I'm thinking of rechambering to something like the classic 300 H&H, that would be a round that would do the M98 justice. The last K98 I restocked, was rebored/rifled from 8x57 to 358/9x57 (will shoot both .356" and .358" bullets)

keeping the original barrel is a good idea, if you can

a few other rounds that are not too common in a Mauser and would be unique, are the 250 Savage, 300 Savage, 358 Winchester, 280 Remington. I'm actually shying away from rechambering anything to 30-06, because there are a ton of Savage 110's and Remington 700's out there now, for $300, in that caliber already. IMHO if one is going to rechamber a M98, it should be something unique. The original 8x57 and 9x57 fit the bill, especially the latter. Even the 7x57 would be a good choice, or 6.5 x 55

if I really "had to" have a 7.62 x 39 bolt action rifle, it would be on the lesser Spanish, Yugo, Czech, Turk Mausers, not on a German or FN action. That latter are just too good to rechamber to a smallish round like the 7.62 x 39. A shot out Spanish, Mexican, or S. American, or Turk-made Mauser would be a good candidate for a 7.62 x 39, by that I mean made there, not the ones made in Germany or Belgium and sold there as contract rifles. The original German and Belgian made Mausers are of such high quality, they are way too nice to waste on a 7.62 x 39 chambering, IMHO.

I saw a German M98 at a gun show, that was rechambered to 30 Luger by the Germans sometime during/after WWII. It was for sale for $125-$150 and no one even wanted it, and it didn't sell. Who wants a bolt action rifle that shoots a pistol round ? That's a lot of extra wood and steel to carry around to shoot a 800-1200 fps. cartridge. It would be an oddity but have very little usefulness except for putting holes in paper, or shooting varmints at 50 yards.

While the 7.62 x 39 is not quite a pistol round, it almost is.

Aside from age, the thread concerns a Yugo M48...
