This case has been watching me.....LOL.... It's about .020 larger in Diameter than the good old .30-06 case and about 3/16" longer and seems to hold a .423 bullet.....(same as the .404 Jeffery) Just wondering if rail work is necessary to feed it through a M-98 Mauser....? /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."

Dog, I just returned from Africa using my Mauser actioned 10.75. It was finished some two years ago and now has in excess of 200rnds through it. Danny Pedersen built one of his beautiful express type barrels and simply screwed it on a VZ24 action. It would feed, but not as smoothly as Rube Well's Type A. Minor ramp and rail mods were accomplished and now it is as smooth as the original Mauser. The bridge has been machined for custom bases, new bolt handle, 3pos safety, Argie bottom metal, etc. 8.5lbs with scope and 3rnds in mag. 2150fps with 400gr AFrames | |||

Some of the guys wanted to see pics of the recovered bullets, so if I can figure out the posting of pics, I will include one of the rifle. | |||

Vapo, I have an original Kynoch case myself sitting on my table glaring at me every day lol. Along with an old 347gr soft point. A friend in NZ aquired one, and was kind enough to ship me a spent case and a pulled bullet. It really is a neat little package. VFR1 is getting good numbers, and I believe Atkinson also had one and has posted some data. I think he was using North Fork 380's If you think every possible niche has been filled already, thank a wildcatter! | |||

The 10.75X68 was the "big bore" offering of the standard actioned Oberndorf commercial sporters. In it's day, the bullets apparently weren't up to snuff although they certainly could have been loaded with the superior bullets of the 404Jeff. if one was so inclined to do so then. Nowdays, it is a great all round choice for a standard length Mauser. As VFR1 mentions, not a ton of work to get one to feed well. The shells fit nicely in an '09 Argentine action I have laying around. Someday... | |||

The origional "404" bullets were a very tapered design so a portion of the nose was bore riding and only a short section of the shank was actual groove dia and as such were usable in all the various sized barrels that were offered by various makers from 418 to 423. This meant there was no great raising of pressures when a 'tight' barrel was encountered. The 10.75 by 68 was much more uniform in barrel dimensions. Woodleigh offers 422 for the Jeffery and 423 for the x68 http://www.woodleighbullets.co...raditional/405q-458q Von Gruff. | |||

[QUOTE]Originally posted by VFR1: Pics of the recovered bullets and rifle. The bullet to the left is from the buff at 80yds. Expanded to .729 with wt retention of 96%. The other two are from the zebra at 150yds, expanded to .705 and .718. Both around 96% wt retention. Another, hopefully larger, pic of the 10.75 in the Moz tall grass.  | |||

I wonder how hard it would be to get a 10.75x68 to feed in a 1895 Winchester. 577 BME 3"500 KILL ALL 358 GREMLIN 404-375 *we band of 45-70ers* (Founder) Single Shot Shooters Society S.S.S.S. (Founder) | |||

VFR1, Curious, what is the recoil like in that rifle? Also, what brass where you using? All I see available is Bertram, but I have heard some negative things about this brass in regards to its "softness". No personal experience. I really have always liked this cartridge, and I have a spare action laying around that needs a barrel, I think a .423 should be in order. If you think every possible niche has been filled already, thank a wildcatter! | |||

Mile high (and others): Your comments on Bertram brass are correct IMO. Huntingtons carries the excellent Horneber brass from Germany but have recently stopped offering 10.75x68 due to lack of interest. I should know as I bought their last cases late last year. You would think if they sold it out they would carry it but who knows. We can buy direct from Horneber. These small amounts of sporting brass do not require an import license. Cost with shipping appeared to be a little more than the Huntington cost. I contacted Dieter Horneber and he gave me shipping costs and procedures. Basically, you have to wire the funds to Germany from your bank and costs are in Euro's. Do a Google search for "Horneber" brass and you will find contact info for Horneber. IIRC, the min order was 100 pieces and at the time it was around $300 including shipping to the US. Not a cheap round considering brass cost, die costs (I also had Lee make a Factory Crimp die for me) but it has appeal. I plan on using 400 grain Woodleighs and Geoff at Woodleigh can provide load data to you. I have the components and will be loading for it this Winter. Regards, RCG | |||

What is the problem with the soft brass anyways? I mean, it is a low pressure round, not running 64,000psi. Just curious RCG, Thanks for the info! That is a bit of a steep price, but with a round like this, 100pc of brass is basically a lifetime supply. Way too cool of a cartridge to really care, plus it seems to do just fine, as VFR1 has proven. I think Atkinson also took some buffs with it, using 350's if I recall...

Perhaps its time RWS was lobbied for a run of brass? Cheers... Con | |||

Con, at RWS's current price for standard cases, I wonder if it would be any more expensive just buying Hornerber? | |||

Milehighshooter, Recoil is minimal, even with a Neidner checkered metal butt plate. My hunting partners were packing heavier rifles. The .505 off sticks would knock the spit out of your mouth. The .510 Wells were a little more pleasant to shoot, but not much. I have both Horneber and Bertram brass. The Bertram is very soft and the rim is much thinner. After sizing, the Bertram brass would not hold a bullet. I had Lee make me a factory crimp die and use the brass for shooting .429 pistol bullets sized to .423. No problem with the Horneber brass. Huntington's has an order in with Horneber but could not tell me when it would arrive. If Bertram is all that will be available in the future, I will rechamber to .404 and load to the original specs. | |||

True ... but may make them a touch easier to source in Australia. Spraggon still import Hornerber here? Cheers... Con | |||

That couild be the issue with Bertram ... if you visit ... you can sort through the seconds bins. Occasionally you'll also be offered from various places unheadstamped brass which is pre-production stuff. Older stuff may have been softer than new production lots, you just dont know what your getting when you buy it as it may have been sitting on the shelf a long time. Cheers... Con | |||

Check out Vaughan Fulton's post in the African Big Game Hunting forum about the 100 pound elephant recently shot in Namibia. The German hunter used a 10.75x68mm double rifle and dropped the elephant with a frontal brain shot. No indication as to what load he used. Mike Wilderness is my cathedral, and hunting is my prayer. | |||

Buffalo arms has 10.75x68 brass made from belted brass, belt and rim turned then formed. I bought some and wasnt sure until I had it in hand, it's excellant stuff! | |||

Just more reason to want one! A bonafide elephant gun that doesn't digest half a can of powder on each shot! I would assume, out of a double, they are not top loads like VFR1 is using either. VFR1, How long was the turn around on the metal work for your rifle from Pederson? I really like that guy, have chatted a few times about reboring, and he does great work.

MileHigh, Danny is an old buddy and did my barrel on a trade for a .416 Rem on a long Sako action. This was a project we had been discussing for a few years and my wife made sure I had it for my 60th birthday. Give him a call at 928-772-4060. Danny built the .505 on the cover of Wieland's latest book and used it on our buff hunt. | |||

I will give him a call about the 10.75! Sounds like you got a pretty good trade there! Sako's are nice, but a custom like yours, priceless If you think every possible niche has been filled already, thank a wildcatter! | |||

MileHigh, I wish I could say it was a trade rifle for rifle. Danny made the bbl and screwed it on the action. A bud in California did the stock work. The bases, bolt handle, safety, rust bluing and final feed work was done by Roger in Atlanta. | |||

Either way, its a gorgeous gun. And functional! I stare at my single 10.75 Kynoch all the time, I am excited about the project If you think every possible niche has been filled already, thank a wildcatter! | |||

Here´s my 10,75 Mauser rifle. My dad builted it in the late 90´s for me. It´s a mid-30´s original Mauser action, with an 24" hammerforged Heym barrel. Last winter, I changed the double set trigger to the new Recknagel trigger.  Martin | |||

How about the same bullets(423) out of the barrel at the same speed for a *LOT* less money? A 10.75x68 holds 95.1grs of water and a 425 Express (300 Win Mag x.423) holds 95.6grs. As the 10.75x68 has a shorter OAL than a 338Win Mag-300Win Mag-7mmRem Mag any action for those cases could be used without any modification. Even at C & H Dies the 425 Ex dies are $60 cheaper and and it uses a $3 shell holder. You have to start with a .423' barrel so that cost should be the same and the brass for the 425 EX would be about 1/5 the cost of the 10.75x68,if you can find it. What you can do is have the barrel marked 10.75x68 and not let anyone see the cases. | |||

Well marking the barrel with something that doesn't match the cases can be trouble with international travel  Plus there is the decided "cool" factor of an old workhorse like the 10.75, plus, I believe you could get at least 1 more case in the magazine, maybe VFR1 can elaborate?Most of what I have read about the 425 also mentions some rather sharp recoil. I am sure that is "matching" the 404 modern ballistics, maybe if it was downloaded it would be more of a heavy push like the 10.75 eh? Hey VRF1, maybe thats a direction you could go if brass dries up? If you think every possible niche has been filled already, thank a wildcatter! | |||

Big Bore Fan I really like that stock profile.   Doug Humbarger NRA Life member Tonkin Gulf Yacht Club 72'73. Yankee Station Try to look unimportant. Your enemy might be low on ammo. | |||

MHS: same weight rifle +same weight bullet+same weight powder+ same speed = same pounds of kick and same recoil speed. Felt recoil would be a matter of stock fit and recoil pad. | |||

Yes, it´s a very good custom stock, fit on me, like handmade shoes.  Martin | |||
