8mm-06

Strider · 08-13-2003, 07:57 PM

I picked up an old turk and was pondering converting it to an 8mm-06.

Anyone ever done this? Sounded like something to do...

JAMES · 08-13-2003, 09:12 PM

Have not done it and have not seriously considered it, but it certainly seems like a simple conversion. I'm no gunsmith, but the case dimensions of the '06 would appear to make the conversion just a minor ream-job and headspace. I doubt if the '06 chamber pressures would be far from Turk 8mm Surplus levels by much. The magazine is long enough.

I suppose for a reloader, this conversion would make a lot of sense.

Indy · 08-13-2003, 10:53 PM

There is an article in the August "Handloader" magazine about this cartridge. I had thoughts of converting a Turk while reading it.

You thought of converting Turks? Man, you have guts. Those Turks aren't very open to being converted.

lefty o · 08-14-2003, 01:32 AM

if you trust the reciever, all you need is a reamer and a set of headspace gauges.

JAMES · 08-14-2003, 07:35 PM

Good point, BattleRifleG3. Whatever happened to good ol' Constantinople anyway.....and, the Brits didn't have too much success doing anything with the Turks back in WWI either. Folks wonder why these Terrific Turk Mausers didn't get much use during WWII.....who wanted to test them......from the small end....?

What about the freebore area of the throat, lefty o? Would you need a reamer cut specifically for 8mm-06 or is there a technique for reaming out the far end of the new chamber after using a 30.06 reamer? Or, am I just dumber than a stick?

lefty o · 08-16-2003, 03:40 AM

i would use a reamer for 8mm-06, once you cut the chamber far enough to headspace correctly -your done.

colt45 · 08-16-2003, 09:31 AM

if you use a 30-06 reamer it doesn't center correctly you need a 8mm-06 reamer, good cart. but with todays powders and realoading data a waste of time and money you'll spend more than the gun is worth haveing it rebored and head spaced.
and don't do it on a turk, please!!!!!!!!!
we'll be calling you patch after the darn thing blows up and takes your eye out.

JAMES · 08-16-2003, 10:00 PM

Good point about the 30.06 reamer....the pilot is too small.

I don't believe that Strider intended to rebore the barrel; just ream out the chamber to 8mm-06. Is there loading data published for 8mm-06 which creates very high chamber pressures.....in excess of what Turk Military Surplus generates?

colt45 · 08-17-2003, 10:19 AM

turk recievers and bolts are known to fail with normal 8mm loads increasing the presures to that of a 8mm-06 would not be good for the most part.
the 8mm factory loads at the time the turk was produced where around 37,000 cup.
the 8mm-06 (rechambered 98) (much stronger reciever) is aproching 50,000 cup.
the 8mm-06 was developed and intended for the later 98's with a bore diameter of .323 not the earlier modles wicth include some turks that had the .318 diameter bores.
and yes most new loading manuals have data for the 8mm-06 its comparable to the 30-06.

JAMES · 08-17-2003, 06:21 PM

That's pretty much where I was headed, colt45. The current SAAMI limit for 8X57 Mauser is set at 37,000 in order to account for the possibility of someone loading a modern cartridge in an old .318 barrel Mauser; however, the European specs call for a 50,000 limit that applies to 98 models with .323 barrels. The Kirakale 98-style Large Ring Mausers (manufactured during the late 30's and 40's) and the military loads manufactured for those rifles were certainly not restricted to the SAAMI limit of 37,000.

I certainly agree that serious care and caution should be exercised with regards to earlier Mausers, or to the use of any surplus receiver for that matter. I don't agree, however, with ruling out an entire production series of Large Ring 98 Mauser receivers just because they happen to be from Turkey, or because there are some earlier "Turk" models out there which were not maunfactured with the strength of a 98 model. There's a whole series of '03 Springfields manufactured which are no longer considered acceptable either. That certainly would not deter me from accepting and firing a Springfield, with the right serial number.

colt45 · 08-17-2003, 08:09 PM

true enough, but the cost of rechambering is more than what the gun is worth.

Shaun · 08-18-2003, 12:03 AM

the 8mm 06 is a good idea in fact you can buy new barrels so all you have to do is install a barrell and headspace it. I currently have a couple of old turks that have become 7mm Mauser, 270 win, 30-06 and we have a few in the works that we haven't converted yet. fun project gun

JAMES · 08-18-2003, 10:42 PM

You're right, colt45; but, some of us are just plain nuts.

I've even considered having a Mosin 91/30 with a worn out barrel bored out to .323 cause I don't want it to lose it's identity with a different barrel! An "8X54R" Wildcat..........And, I don't even know how to handload yet! Yahoooo!!!!!

(This is what happens when you work all day in a job that you just can't stand and you ain't proud to be doing......)

colt45 · 08-19-2003, 09:57 PM

been there one of my posts described my last adventure with masuers and rechamberings

Strider · 08-23-2003, 04:53 AM

What the gun is worth isn't really what concerns me here. I don't think you could argue economy for any wildcat conversion. It's more of a learning experience and a fun project.

I read an article someplace (I think it was in a reloading manual) that said all you need is a reamer and headspace gauge. It sounded awfully easy... I suppose I would rather use a German Mauser, but I picked up this turk in a trade and don't really have any money in it.

I'm not a Turk collector, but have read enough to know there are some differences in bore diameter and debates of strength and SAAMI specs to protect the unknowing shooter.

Anyone have practical knowledge/information on the approximate dates or serial numbers and/or how I could determine my rifles potential strength and/or value?

TIA

JAMES · 08-23-2003, 11:33 PM

I'm certainly no expert, but I believe that most of the Turk controversy comes from the apparent quantity of Mauser models that they purchased and placed into service over the years during their long-term relationship with Germany and German Mauser exports, that they seem to have "remanufactured" several models, and that they chose to go with a large ring receiver threaded for small ring barrels in the later models.

I have had absolutely no problems with the WWII era Kirakale M1938's.....large ring with small ring threads. I think that if your Turk is a 1938-1945 Kirakale (considering all other things as well), you probably have a decent base for a good rifle.

Strider · 08-24-2003, 02:15 AM

Interestingly, I also have a German Mauser that was rebarreled with an 03-A3 Barrel. So it's a 30-06. It's a pretty interesting piece. Well used but mechanically sound and good headspace. I've done quite a bit of work to get the old custom stock rebedded and in order. I plan to take it out this year and see what kind of groups I get.

Shaun, Where did you pick up your barrels? Online?

TIA

Isn't much of a wildcat. Been around for a long time. That's what a Steyr M95 shoots.
