    I'm considering building the Mauser K98k into a scout rifle. As I'm a poor man, I appreciate caliber commonality. How do I go about converting the K98 into a thirty-ought? I want the work done by a professional gunsmith, of course, I'm just curious if it's been done successfully before.

    Thanks

    Will require a new barrel as a k-98 is a larger caliber bore.

    Why not just buy a Colombian or Peruvian. They are already in 30.06.

    You're going to need a new barrel and $$ for the gunsmith to install. You're looking at about $150 for the barrel and another $100 or better to install and another $50+ to reblue.
    Add to that the money you spent on the K98 and you're well into the cost of a Ruger Scout, FWIW.

    There's more to it than just a new barrel.

    You will need to lengthen the magazine box to accept the longer cartridge.
    There are several methods, but the most common is to saw the front of the box down the two front corners, move the front forward the right amount and weld it back together.
    In doing this, you only saw down to near the bottom of the box, but leave a small amount at the bottom. You then just bend the front of the magazine box forward, then weld it.

    You usually have to move the lower rear edge of the feed ramp in the receiver forward by grinding, but you can't go very far, since this ramp is also the rear portion of the lower locking lug.

    If you intend to load with a stripper clip you'll need to cut a "half moon" cut through the rear edge of the receiver ring to clear the bullet noses.

    If you want to use the military rear sight, you may need to change it or the sight bed as well.

    All this is very well explained and illustrated in Jerry Kuhnhausen's book "The Mauser Rifles M91 to M98: A Shop Manual". Money well spent.

    You might as well go buy a new Savage. You're going to have to scrap everything on that K98, but the action and build it from the ground up. That's expensive if you don't run a machine shop and aren't a good machinist/gunsmith not to mention stock maker.

    It has been done before, back in the 40s and 50s when K98 surplus actions were 5 bucks and gunsmiths worked for less money. People who build custom guns on Mauser actions now days are generally well healed and just WANT a custom rifle.

    "You will need to lengthen the magazine box to accept the longer cartridge." NO you wont the original box magazines accommodate the .06 very well as is. ( I have that book in front of me now) I respect Jerry's knowledge very much but he is wrong in this case. You will have to do this if you go to a magnum caliber however.

    It will cost you as much or more to build the rfile vs buying one already in teh configuration you want.

    You can ream it out to 8mm-'06 and roll your own loads. That was the 1940s/1950s poor-boy solution.

    what kind of K98k? Hell if it's a good one , non RC with matching number i'll buy it off of you and give you more than enough money to get a Savage 110 chambered in .30-06.

    and i just bought 1500 rounds of 8x57 last week for $135, keep your eyes open, cheap 8mm surplus are still out there

    I'm really just looking for a nice platform upon which to build a thirty-ought Scout rifle and I've seen a few nice Mauser builds. The builds I've seen didn't change the caliber. If I'm paying the money to get the rifle done the way I want, I might as well pay for it to use the caliber I prefer.

    i'm just saying you might want to consider what kind of K98k you're buildling the scout rifle out of. IF it's an average mix master RC, then go for it, but if you happen to have a matching bringback rifle with a rare code it would be a VERY bad idea to modify the gun.

    just my 2 cents

    You can convert the M98 into almost any caliber made. I have them that I have built in 30.06,.308,.280 Rem. and .257 Roberts. All but one were rebarreled(done by Jim Mccullough of Selma,Al.). The one 30.06 with the original barrel is Colombian. I also have 2 in 7x57. One is a Chinese (Chaing Kai Shek)action with a new 18'' Latin contract barrel. The other is a 1912 Mexican with a new #2 contour Douglas barrel. The M98 is an excellent platform to build on but as gun addict says make sure you aren't cutting up a collector piece.

    The action has been used for just about everything that will fit in it. There are many custom Mauser-based rifles out there.

    These are generally not for the self-proclaimed "poor".:)

    Do you handload?

    If so, I'd just get some 8mm brass and dies. Apart from the initial cost of the dies, it shouldn't cost any more to shoot 8mm than .30-06.

    Of course, if you are serious about building a Cooper Scout Rifle, it'll be pretty hard to build it from a K98 IMO. I'm not saying someone can't, but I doubt it would be worth doing if you care about the cost.

    For one thing, the spec is 6.6 lbs. max, with scope and sling, pretty much by definition a short-action carbine.

    Getcha' an FR-8. Nice handy-short rifle in .308. It'd make a purrfect scout rifle. Last one I had I paid $125. for, and what a good shooter it was. (so good that I sold it for $350. but still kind of regret doing that).

    Ok so I am going to ask a silly question, but why change to 30-06? Does it really offer that much of a gain over a well loaded 8mm? I ask because I really do not know. I have to agree with Art, a re-chamber to 8-06 might be easier than going totally over to 30-06... says the guy that wants to build his VZ24 into a 35 Whelen....

    Not enough difference in a good 8x57 load and the ought six, to get excited about. Only limiting factor is bullet choice, but there are enough good 8mm bullets on the market to whip-up some great 8x57 loads.

    That'd be my approach to this project.

    Already have a 20" barreled M98, but it's not a "scout" rifle. Very handy, very accurate. All that was involved aside from the usual chores for mounting a scope, bolt handle reshaping, replacing the trigger and safety, was cutting the original barrel to 20" and crowning the muzzle.

    Far less expensive than springing for a new barrel and the extra 'smithing. There are now "scout" scope mounts offered, that can be installed in the original M98 rear sight housing with little effort.

    IME every bullet you stick in an '06 shoots to a different POI. Generally, you find a bullet you like and your gun likes, and stick with it -- maybe two or three for different game, but no more than that.

    Therefore, dizzying bullet selection isn't the most important thing in the world. If anything, the choices can be overwhelming when you want to work up a .30-06 load.:)

    ...which isn't to say I'd choose to build a Scout from a K98k...

    Ammunition to go HAD 3 commercial (soft point) loads for the 8x57. 139gr.,170gr and 196 gr. That should pretty much cover the spectrum. Notice I said HAD,I just went there and the 196gr Prvi Partizan was all that was left.

    The surplus M98 is about the perfect platform to build a scout rifle on, especially if one reloads: Great choice of cartridge; no real gunsmithing required and there are many to choose from, usually at decent prices.

    Not as many choices as years ago, but there are still milsurp M98s around for less than most used bolt action sporters. Cutting/crowning a M98 barrel isn't much of a challenge for anyone that's handy with tools and can follow basic instructions. If ya start with a K98, probably no reason to even shorten the barrel?

    A 9 lb. scoped long-action rifle isn't a "Scout Rifle". (I hunt with a scoped .30-06 that might come in at 9 lbs. total -- nothing wrong with it, but it's not a "Scout Rifle".)

    I don't think JC is JC, but I figured the OP wants something specific if he uses the term.:)

    Why would it need to weigh 9lbs?

    My 20" barreled K98 weights far less than 8lbs, with an old Fajen walnut sporter stock and 3x9x40 scope. Although I eliminated a few ounces, when I lopped-off the ugly black plastic fore end cap on the stock and reshaped it?

    Most folks would install a synthetic, if they wanted a lighter M98 scout rifle, instead of letting the full mil stock on it? Midway regularly has Ramlines on sale for the M98 and other rifles. Got one two years ago from them, for $69+ shipping, on a monthly special.

    Besides, the OP stated that he was dealing with a K98, so apparently he has no qualms about one in a scout rifle configuration?
