i was wanting to know if it would be okay to rechamber a turk mauser to 338-06? i know that this is found in a large ring barrel, but i also know that the turk barrel is a small ring diameter. will it work? thanks guys, brian
 
You can't "rechamber" an 8x57 to .338 anything. The 8mm bullet is .323", the .338 bullet is .338". You could rebarrel, but I admit to super caution and would not recommend it with that action. (Another consideration is the end value; if you spend a lot of money on a new barrel and other upgrades, it will still be a small ring Turkish Mauser.)

Agree with Jim K. Unless you can do the work yourself, it would be a silk purse out of a sow's ear project. Brownell's sells Turk barrels in .308 and .30-06 for $225 and you still have to finish ream and headspace them.
 
i should have said more.

question 1... what do you mean by "extream caution" woth of the rifle as of resale value means notta to me. id rather have a rifle that i built myself do a good job rather than buying a savage in .308 that anyone can go buy.

question 2....
i was considering a re-barrel job. i can do it myself, i have lathe accsess. i would get a barrel blank, conture (if not already) , thread, chamber myself. would save a alot of money. i was just wanting to know if the 338-06, or just the 06 brass would be to large for the action. meaning... would the tenon have addiquate wall sthickness for the chamber? but... if what said abpve is true... about turk barrels in 30-06, i think that it would be okay.

what twist rate would you guys recommend for the larger, 200-300 grn pills??

thank guys, brian
 
It's a .30-06 cartridge necked up to .338 it should fit in that receiver. I have not loaded rounds for any of these.

There's the 8mm-06 wildcat that allowed .30-06 brass to be used in rechambered 8mm rifles after WWII. I suppose OAL would be the deciding factor but I can't find an online page with good technical info not that I'd trust an online source. I don't know the maximum OAL for that particular rifle so that it will feed and function.

You might contact one of the reloading equipment companies for information. RCBS came up with an improved variant of that cartridge so they had reamers for it at some point.

This has the case drawings along with some improved variants.

This has some OAL numbers for .338-06

Maybe 3.25in OAL but I don't have a reloading book near me for 8mm Mauser http://en.wikipedia.org/wiki/7.92_x_57_mm

Check out Kuhnhausen's book on the Mauser series rifles. The only tro I can recall is the 30-06 is longer than the 8mm and the magazine well in the Mauser needs to be enlarged to handle the additional length. Other than that, I don't think there is a problem.

if a factory cartridge fits......

If a factory 30-06 fits, the magazine as the rifle is now.

Make your project!

The smaller barrel shank is not a problem, with any case that uses the standard head size, IE 8X57, 30-06, 308, etc..........

If the smaller barrel shank was a problem, all the Small ring Mexican 98's would have failed years ago! I don't know of any that have, And I know of at least 3 that have shot out at least one barrel each and 2 of those are at least 3 barrels each. 22-250's are the first choice of barrel for most of these actions, and make as much chamber pressure as the '06, so do the 243's and 308's the second and third choices!
 
I agree with Big Al. Just because the Turks are presently easy to acquire
doesn't mean they don't have value. That action is a time proven
engineering masterpiece. Your lucky to have access to the equipment
and the expertise to use it. Go for it!
 
The 338/06 is a 3.34" cartridge that is too long for the mag well.
The 1938 Turks can be lengthened easy enough, but the 1903 Turks have already been lengthened from 7.65x53 to 8x57 and are harder.
 
whats the best way to lenghten the mag well? and... what should it be lengthened to??? im guessing a little over 3.34"? maybe 3.45"?
 
I keep milling both ends until it works with dummy ammo.
Round nose ammo is cheating.
The pointed nose is the hardest to get to feed.

What is the mag length

You have not posted the length of the mag, what is it? just for reference.

Also you are doing a Straight wildcat conversion, a true handload, no factory ammo available wildcat. So if it takes loading to an overall length of say 3.15to have cartridges that fit and feed, WHAT WOULD THAT MATTER, it is not as if you are able to run out to the store and buy a box of shells, only to have shells that jam in the mag!!!!!

Modifying the overall length of the loaded cartridge, a problem? I think not! Get a hold of a book the lists a lot of wildcats try counting the ones that move the shoulders away from being able to use standard chamber gauges!!!!!!!!!

All that is needed is to know how to work up safe loads, and to be able to repeat then. Because anyone that doesn't have this ability should never try reload anything!!!!!!!!!!
