Left Hand Magnum Mauser Bolt Assembly
      #66688 - 10/12/06 04:14 AM

I have a PO Ackley imported, Japanese made 98 Magnum Mauser receiver and I need a bolt assembly for it. I have had this thing for 25+ years and have checked all the usual suspects, Dakota, Granite Mtn., NEGC, Mauser and many others. I finally located and purchased a left hand, standard length, large ring, commercial Mauser action complete with magnum bolt assembly, bottom metal, trigger, etc.

I was recently told by a friend that the bolt length is the same for both standard and magnum receivers and they are interchangeable. I question this, and am hoping one of you regulars at this forum can give me a little guidance.

Is this the case? Are the bolts interchangeable between standard and magnum length receivers? If not, where can I get the left hand bolt assembly? Bottom metal, trigger, etc are pretty easy to come by, but I gotta have that pesky bolt first.

If none of the above is possible, I still can build my DG rifle around this standard action in 458 Win Mag rather than 458 Lott that requires the magnum action.

Your patience with me and my ignorance is appreciated. Any advise/suggestions will be appreciated.

Thanks................Lee

Hi Lee; I have been led to believe that all the standard lenght, large ring 98 parts are usaully interchangeable, the difference is the bolt face + extractor + magazine well etc. have to opened up from a standard cartridge to a magnum. Since have a bolt just try it if it works go from there, unless it is a custom made action it should work. I would think the main criteria would be that the locking lugs engage the action properly - probably a job for a good smithy. --- John303

John303,

Thanks for your input. Here's hoping all goes according to plan. I should receive the action I purchased in a few more days. Checks have to clear, the seller has to remember to ship it, etc. You know how slow these things are. I've been waiting 20+ years, a few more days is no big deal.

I will try to post pictures if successful.

Thanks again and Merry Christmas...............Lee

The diameter of the bolt for both standard and magnum length mausers was the same, but sadly not the length, the length of the Magnum mauser bolt was approximately .75" longer than that found on the standard M98 as was the distance between action screws.

Consequently the bolt from a Standard length Mauser will not work in a Magnum action.

you can still build a serviceable Lott on a standard length action, a True Magnum length action is NOT required, there are many such guns in this calibre on the standards 98 action giving sterling service.

The magazine well will need opening from the standard length to accept the longer rounds but done properly and without taking too much material from behind the front bolt lugs no real problems should be encountered.

Bottom metal to suit the Lott round can be obtained from Prechtl in Germany or Ted Blackburn in the U.S

JTomlinson,

Sounds like you really know some stuff! This is just the kind of information I have been missing for years. Where can I find some technical data, i.e. drawings, measurements for the '98? As it turns out, I may not have a magnum after all. I could have been misled by the man I bought the action from. Who knows?

Anyway, thanks again for your concise reply. This is what I have been looking for all along.

Lee

wellplugger:
You MUST get a copy of Jerry Kuhnhausen's shop manual on the Mauser Bolt Actions. Brownells can sell you a copy (stock no. 924-400-098), or Midway, among others. I have had mine for over a decade it seems, it is oil-stained and dog-eared, just like a good workshop manual should be!

Just re-checked my references source, the bolt on the commercial Mauser Magnum was 6.770" long cf 6.370" on the DWM 09 Argentine and Standard M98 Oberndorf actions.

The distance betwen the magazine screws was however the same for both magnum and standard length actions at 7.835", sorry for suggesting otherwise

As Marakai says the book "The Mauser Bolt Actions ~ A Shop Manual by Jerry Kuhnhausen is possibly the best book on the subject.

JTomlinson and Marrakai,

My book is on order. Thanks again for your insight. I received my action and it is a Daly Zastava with magnum bolt face for 300 Win Mag size rounds. It has a "side" style trigger safety. The action is a little stiff internally, but the exterior finish is lovely. With some polishing of the slide rails, etc. it will make a fantastic DG rifle.

Any ideas where I might get a 3-position Mod 70 style safety made for my lefty? I might even consider a military style just for the classic look. In the end, it is just going to come down to what I can get. Being left handed is a real pain in the you-know-what when it comes to guns and the shooting sports.

I hope you guys don't mind my constant questions. I am certainly a novice and really appreciate your help.

Thanks again....................Lee

When you say left hand Mauser are you meaning a left stocked rifle with a r/h action or have you located a true l/h mauser clone, I am guessing that as you say it is a Zastava action, then it is a right handed mauser action?!

I am left handed and have an ecclectic mix of both true l/h rifles and some on Standard length 98 actions that I simply use from my left shoulder without too much problem whatsoever.

The safety you mention, viz Model 70 3 position are offered for Mauser actions either as a safety lever for gunsmith installation via a horizontal slot milled into the bolt sleeve or alternatively as a full replacement bolt sleeve just requiring blacking and fitting to the bolt. On both variants the lever tends to sit to the right hand side of the bolt (i.e the same siide as the bolt handle) but seem convenient to use by a southpaw like ourselves!!

Take a look in the on-line catalogue for Brownells (www.brownells.com) they have a number on offer and by looking at these you will get a better idea of what is available and how it will look on your gun.

Hope this helps

Jonathan

Jonathan,

I posted a long answer yesterday and it did not show up. Technology "ain't it grand". Or could it be a "senior moment" on my part. Who knows?

Anyway, I have two left hand actions now(almost). One is the receiver only and the other is the Daly Zastava. Both are true left hand operation with bolt, etc. on the left side. A few years ago, I made a decision to not purchase any righties (rifles that is) for my personal use. I have bought a few, but these are for my son's as gifts, etc. We as left handers have to compromise/adapt to the whole world as it is. We always have to modify our life to use right handed implements and not get what is comfortable for us to use. Enough with the whining on my "soap box".

As I say above, both actions are true lefties. I have seen the aftermarket safety systems you mentioned and like the look of all. My only concern is that all my rifles have the safety on the left side. I suppose I could get used to it, but on a DG rifle, familiarity and flawless operation are paramount. Again, we are almost forced to adapt. Additionally, I'm not sure if the right handed versions will even fit on the left hand bolt. The threads on my bolt sleeve are left handed and that makes me think the right handed versions will be threaded with right hand threads. I ordered the Mauser book recommended above and hope it will shed some light on the subject. You mention above the the design of the system; milled slot, etc. I have an extra bolt sleeve if you have a gunsmith that can do the work.

Thanks again for your help..................Merry Christmas..........Lee

I understand you now, although I have never come across that particular action myself. The rifles I have are either on Model 70 L/h, Dakota 76 Actions or the non CRF feed Heym from Germany.

I think a number of riflemakers in the U.S could help you out and one in particular could be Denis Olson, a side model 70 safety catch in l/h should pose no problem although the orientation of the lever may mean one has to be made rather than merely bought off the shelf from Brownells.

Alternatively, if the bolt sleeve and cocking piece are identical in dimension and manufacture to those found on Mauser actions, then you could fit a Buehler safety catch, this fits in the same way as the flag safety catch of the original Mausers, but swings through oinly a 55-60* arc rather than 180* as did the flag safety, the beauty of this type of safety is that it can be fitted and still operate safely below a low mounted scope, although again I feel it will be designed to operate on the right hand side of your rifle, which is possibly not what you want.

There are makers here that could do the work, but it would be more cost effective I feel to get the work done in the U.S.

A further thought you could look up Jim Wisner or Ted Blackburn (Precise Metalsmithing Enterprises) both these people make replacement components for Mauser rifles and there exists the possibility that either of them may have or be able to make what you seek, I am sorry I don't have e-mail addresses for them but Think you will find them from the website.

Good luck in your quest and all best wishes for a Merry Christmas and prosperous 2007

Jonathan

Jonathan,

I am a bit jealous as I have "lusted" after a Dakota since they first came out. Not quite in my budget yet. Maybe someday after I get my sons out of college or I win the lottery. Heck, getting my boys out of college may be just like winning the lottery..........lol.

I will Google the gentlemen you mention and try to contact them. Thanks again for your help. I will post again as I progress.

Jonathan,

I am one happy camper. After some surfing the web, I found exactly what I want at the following:

www.huntamerica.com

From this site, look on the left side of the page for "David Gentry 3-position Safety" link. He makes left and right handed Mod 70 style replacements for the Mauser 98 at $155.00 ($162.55 delivered). I just completed my order. They also make replacements for the Mod 700 Rem. as well.

Of course, it takes some gunsmith work to install, but that should not be too costly.

Thanks..................Lee

Thats good news indeed, on the way home last p.m from work I thought of a few further names I should have suggested and whilst Gentry was not one I have used some of his muzzle brakes in the past and they are a nice made job that work well, it will look good once installed.

It is surprising what a little time spent on the internet can throw up, Now if only I could find a H&H Royal De-Luxe in .500 N.E for under £500 !!

Let me know how it fits as I have a Mauser still with the right hand safety that may benefit from such a change in the future.

Jonathan,

I'll bid £501 on it if you do find one...lol. I don't care if it is right handed or not.

I'm sending my action off today to get the safety installed. If it is as nice as they appear to be on the web, I plan to change my 2 Rem 700's over as well.

Will keep you advised................Lee

Jonathan,

Further update to the David Gentry story. When I asked him if he could make me a bolt assembly for my Ackley, he casually replied "yes, that should not be a problem". I almost jumped out of my chair. After all these years, finally someone willing to build what I want. I got a quote from him and it is very reasonable at ± $600 US to include bolt body, extractor, shroud, cocking piece, firing pin, 3-position safety and fitting to my receiver. I am sending the piece off today. I should have it in hand in a month or so.

He builds his own M98 pattern actions as a basis for his custom guns so building my bolt is "business as usual" for him.

Thanks for all your comments and Merry Christmas...............Lee
