You good people got me in to this, had to make a .500 Jeffery from a standard Mauser.. Believe me it feeds like a dream. My ´smith and me had a couple of years to think this through, and because my stock was a standard one AND I did not want a Schüler mag, but a staggered one, our solution was to have a mag that would hold three rounds of which one will be loaded at the closing of the bolt (1+2). So after some thought we made this    The frame goes in the stock from the top - and it works surprisingly perfect, only because of the splendid help from you good people on these forums, especially Alf. Thanks a lot for your help. The inscription on the rifle:  I admit the text is too large, but this was a misunderstanding on the engravers part, not being used to engraving rifles.. I decided on the ".500 Jeffery" text, but being somewhat in the business of law I wanted it all to be right , as the chamber really is a Schüler, so I put in the 12,7x70 text too.. the sighting was a problem as the gunsmith did not get my chronograph to work, we ended up at was somewhere noted as maxload; 113 grs of Vihtavuori N140 535 grs Woodleigh = 2540 fps  OOPS, freaking Battleship Missouri!!! So we backed down to 102,5 grs = 2310 fps, which is quite enough for a this rifle.   Thanks for all your help - this is one FANTASTIC rifle! One grateful Boha | ||

That is beautiful!! Is it well bedded to prevent the stock from splitting? lawndart  | |||

Thanks! I am so really happy about this one - it just feels so right. A smooth tool.   Oh yes Lawndart, metal behind the recievers lug and the one under the rear sight, aswell as between mag and the trigger; and a piece of metal bored into the pistol grip. 600 grams of lead in the buttstock. BALANCE! | |||

Ummmm what does a rifle like that cost? I'd sure love a 404J. the chef | |||

Don´t ask. Cannot tell you. I purchased the material in 02 - 03 and payed for the work by checkering and finishing other stocks. But this is mine!! Oh, we made a 404 too on a standard Mauser back in -03:  here´s my PH Ryno saying IHRR! HOLD IT FIRM, when we had fun taking down a tree with it.. | |||

boha You have executed the build of this rifle really well. The wood and metal work look the way I want my personal rifles to finish up. I am in the process of building a 500 A-Square and would like to hear your thoughts regarding a few areas of the rifle: 1) How do you find the stock design when you fire the rifle, especially during recoil where the top of the stock meets your cheek? 2) How heavy is the rifle and what barrel dimensions did you use? 3) How do you find shooting the rifle with loads through the lighter to heavier charge weights, eg the 102 gns of Vit vs the 113 gns of Vit? Thanks Fergus | |||

Fergus, as you can see the stock is rather straight and the comb is not "german" as in hitting your chin. It does not hit my chin. The stock is a pre formed one I got from Waffen-Schweigert Augsburg Germany, his English version - simply beautiful and very practical recoil-wise. It does not hurt you (unless you like excessive big bore rapid un-loading..) The drop is optimal for me. A look at Alf´s original Jeffery will show another type of drop. It is all individual. The wheight is mentioned above. The barrel dimensions are roughly 1,2" in the reciever end and .80 muzzle, 24" barrel The max charge is excessive, Penetration of a sufficient scale is achieved at 2200 - 2300 fps. No more is required. If you do not believe me, ask "Doctari" Robertson. He will have the answer. The rifle can be handled at 2300 fps. At 2550 fps it can not be handled. That´s gospel. | |||

Thats very very nice !! I would like to have a .500 J with nice trimmings like that. I like the idea of having your load that the sights are regualted for on the gun as well !! | |||

Boha Thanks for the information. I certainly plan to run my 500 A-2 at velocities no hotter than 2200-2300 fps. Thanks again Fergus | |||

Alf, Can you tell us how you managed to set back the lugs on a .500 Jeffery using loading data published on these pages? Was your .500 Jeffery a Standard Mauser 98 or a Magnum M98??? You are the one that convinced me that lengthening the Standard M98 to H&H length is a no-no! | |||
|
| one of us |
The .500 A2 in a Magnum Length action is best at 2400 to 2450 fps with 570 grainers, using RL-15 in my load testing. 2200 to 2300 fps with the .510/570 grain bullet will certainly do any hunting duty imaginable, however. | |||

Thanks for the pictures, boha. To your health. | |||

That was my thinking. The 500 Nitro seems to do the job at less than 2200 fps, so I didnt see the need to push harder than that. Fergus | |||

Nice rifle, boha. What are those pins protruding from the follower? Are they bearings? Do they ride in grooves in the magazine box? Mike Wilderness is my cathedral, and hunting is my prayer. | |||

You're not the first to get bull shit loads on the AR forums....a warning to all.....if it seems to good to be true it probably is!!!

10# 10.75oz I have a jeffe, and at that weight and 2300, it's rather just fun.. remember, that's actually "just" a 458 lott with 20 more grains of powder...500 vs 535 gr 2400 in a nearly 11# rifle is a good match, seriously.. 2550 is nothing for that case, with the right powder... that is, looking at it from 700gr at 2150 in an 11# 550 express. or 665 at 2200+.... excellent rifle,,, wish i had about 1000 more pictures of it "naked" .. sans stock jeffe opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

Boha, We have to make a plan! I will try to convince some people that we also need a .500 Jeffery on our tour to Zim Husky | |||

Boha- Beautiful gun! I just love the looks of a big bore on a M98. Properly balanced they are a dream to carry. Well done and thank you for sharing it with us. A word of warning on M98 actions though. I've managed to set back the lugs of quite a few during my big bore experimentation. I may not happen till the first few hundred rounds go through the gun or it may happen on shot number one. In addition, lapping the lugs on a Mauser is a big no-no as you are intentionally cutting through ther case hardening on both the bolt and action locking surfaces. Remember, these actions were designed for a military action generating about 45Kpsi. They were case hardened actions only, with about .003 deep case hardening and soft steel underneath. The steels and the case hardening techniques of the time were somewhat eratic also. When you up the case head diameter( bolt thrust) and pressures into the 50-60Kpsi range. You will eventually begin to observe action lug set-back made obvious either through sticky bolts or unusual cartridge expansion. Luckily, I have never had or seen a catastrophic action failure.This is also exactly why Weatherby stopped using FN mauser actions on his 300WBY line. With that said, I have seen some VZ-24 actions used to build some big guns which seem to not set the lugs back. Apparantly, the steel and hardening techniques became much better when the VZ-24 was produced. I have had some metalalurgical analysis done on a few Mausers and then had them re-heat treated locally. This is of course a best guess approach, but so far no problems. This is the only military Mauser action I use to build big bores on. There are better choices, but none result in a rifle so easy to carry and with those beautiful classic lines.-Rob Never underestimate the power of stupid people in large numbers to do incredibly stupid things- AH (1941)- Harry Reid (aka Smeagle) 2012 Nothing Up my sleeves but never without a plan and never ever without a surprise! | |||

The pins were put there to hold the first round to the left. We planned to replace the pins with a full length piece og metal, but the pins work so well we decided not to. There are no grooves in the box. Oh and Husky, I go with the rifle - separation is not an option..  Boha | |||
