Making a 8x57 Mauser

[cdet69]

Has anyone here ever made a 8x57 Mauser on a modern action? I have a chance to get a Remington 700 action and was thinking of turning it into one. It would be my cast bullet shooter but would like a twist rate that could be used for j bullets.

As long as you are starting with a 06 length action it should work fine. Typical 8mm twist is about 1-9.75 give or take. Shaw lists theirs at 9.5, Shilen and Douglas at 10 and either should stabilize well enough unless you are going for a really long boolit. Mine is a Yugo Mauser and it shoots cast just fine as is so I would not fret it.

Keep in mind that 16 twist is standard for the 32 Winchester. It works fine for any 170 grain rounder nosed projectile. So, consider first what projectile is to be used most often. Increase twist for incremental heavier projectiles. Have the barrel made with higher lands, such as 0.0045-0.0050 would be my advise to be more like the military barrels. ... felix

Remington made a "one year" run of 8x57's. I have one, it's a 4 groove brl and it shoots GREAT I could not tell you what the twist is but you could probably look it up and use that as a guide.

It shoots cast and jacketed just superbely.

If I remember correctly a mauser action is between a long action and a short action. SO as long as its a long action should be fine. Because of its length is why the 7mm Mauser (7x57) never took off in the states because of its "odd size" and being right between the .280 and 7mm-08. 8mm mauser had a similar story in standard actions.

Should still be a fun project

Often copied but never improved. Paul Mauser new what he was doing. BTW the 700 is a modified copy of the 98 Mauser. I have a 98 in 8MM and it shoots cast and J words just fine. Also I am in the process of building my third rifle on the 98 Mauser action. The 98 is a long action. Some of the Yugo's are a mid length action. See my post in "special projects" "Here I go Again" for pics and details so far. Had to put it on the back burner till after the holidays.
Your project is easily doable. Just get a large ring Mauser barrel and turn the threads down. Both are 12 threads per inch but the Mauser is 55 Degree and the 700 is 60 degree threads. By the time you get the threads cleaned up to 60 Degrees, you will be real close to the right diameter to screw into the receiver.
Keep us posted. and good luck.

Hear! Hear!! I have one and it is fantastic. Regularly puts Hornady 170 gr RNSP into 2-3 inches at 200 yds fueled by a max dose of Benchmark powder. It is my favorite rifle and a prized possession. I believe it is a 1 in 9 twist, but I would need to measure. Does very well with my NOS 198 gr ballistic tips. I don't think you'll be disappointed at all going the route you're going by making a 8X57 on a Remington 700 action.

Yep plenty modern in my book. Here is a CZ (Brno) made Persian 98/29 with barrel cut to 24" and restocked in good AAA black walnut. The light is at the wrong angle to show the good wood in this pic. I will try again some day. Oh yes, 8 X 57 of course and it is a cast bullet shooting wonder. IIRC factory barrel twist is 1-9.7 on these rifles.

[Blammer]

if you need a mauser action for a doner let me know I have a bunch of old milsurps that may work well for you. :)

as they are already chambered and set up for 8mm... :)

I had ER Shaw build this one for me on a Turk 98 action. It is a #7 barrel contour and was very heavy. It took a while to break in and shoot without fouling. But when it finally had about 300 rounds of jacketed through it, it smoothed up nicely. It would shoot in the .2-.3's with 200 gr SMK and 51 gr of IMR4350.

Here is a barrel you could use for your project. http://www.copesdistributing.com/blow-yugo-original-virgin-barrel-p-4661.html

Is that the one that sold on here a couple years back? I will always regret not buying that one...

[tomme boy]

Yep. I wish I never sold it now.

Where was the stock obtained, Tomme? I have several of the Turk actions waiting to be turned into something else and I have not been able to find a good source for the intermediate length actions.

Thanks,
Doc

[tomme boy]

Turks should be a 98 long action with a small ring thread. The Yugo's had the intermediate length 98 actions from what I remember. I built a bunch of them on Boyds stocks and Richards Microfit. I had the first stock they cut for the Yugo 98.

Here is the Richards Microfit Yugo in 257 Roberts.

Richards stocks are not for the beginner. They take a lot of finish work to be usable. They come to you like a beaver chewed the blank.

The stock on the laminate above was a Fajen walking varminiter if I remember right. I had to really hog out the barrel channel for that heavy barrel.

Stocks: for 95% pantagraphed stocks check with: www.walnutgrovegunstocks.com. He has over 100 M98 variations stocks. Including the YUGO 1948. I know, because he used my Guild Mauser stock for his master pattern.

[nekshot]

a mauser redone as that just looks right! I also ordered a 8mm barrel from cope for one of my sons actions. I said why screw around with a military throat wear and tear when we can get a new one. Patiently waiting.

[Bodydoc447]

Thanks, guys! I am going to put some time into turning a Turk into a .257 Roberts and a Yugo 48A into a sporter 8x57. Appreciate the help.

Doc

[Blammer]

I have turks and Yugos and others too for sale. :)

[TNsailorman]

Doc, may I offer a suggestion? Consider making the .257 an Ackley Improved version. It is about the most efficient of all the Ackley improved versions. I was told that by Parker himself. It will get you within 150fps of the .25-06 using the same weight bullets and use less powder doing it. You can still shoot regular .257 Roberts ammo in it also.

[Bodydoc447]

TNSailorman,

I will look into the 257 Improved. I already have a .25-06. I have a thing for the quarter bores. No real rationale, I just like them. Same reason I love my .41 magnum. I appreciate the suggestions.

Doc

I already have the actions, just haven't had the time to do much with them. Good actions, especially for this sort of thing.

Fixed it for you, Larry.

Folks, I've got Remington 700s, 722s, 600s, even 40Xs. Even got a Winchester M70 and a Hart A10.

None of them are much "better" than a 98 Mauser. Tighter, closer tolerance, yes. A little stronger, quite possible.

But, a 98 Mauser is strong enough. And tight enough for most work. Sheesh, even some have been turned into varmint rifles and bench guns, in the past.

It it were me and I wanted an 8mm, I would put my hands on a 98 with a good barrel already, and build a sporter.

Oh yeah, I have a 98 or two in 8mm. 93/95 in 7mm too.

By the way, I have a Remington 600 in 257 Roberts. I like it, hunt deer with it. No, it couldn't be original, they didn't make that caliber in that model. Looks better without the rib anyways.
