My search is over - my newly acquired 11.2x72 Schuler Mauser

Hello All,

By now you have seen my post about the 11mm Johan Peterlongo Mauser, and my disappointment in finding it was actually an 8x57I - and not an 11mm. (see that post here) http://forums.nitroexpress.com/showflat.php?Cat=0&Number=374431&an=0&page=0#Post374431

Well, jgrabow a fellow Forum member on this forum, saw my plea that very same day of my post. He emailed me and generously offered to sell me his 11.2x72 original Schuler that he purchased about 15 years ago. Turns out he was also from Wisconsin. The next day I jumped in the car and drove 5 hours north to meet him. What a wonderful man. I must give a big shout-out THANK YOU to him for passing-on this wonderful treasure.

The rifle is now in its new home here with me. Here is the original ad from when he purchased the rifle. He took very good care of it and its still in the same remarkable condition as when he bought it. The rifle came with RCBS reloading dies, 35 loaded rounds, 12 empty brass, and 475 assorted bullets consisting of 125 Woodleigh, 125 SAF Raptors, and 225 assorted softs and solids.

As a side note, jgrabow also has a gorgeous 10.75x68 type B Mauser for sale.

As always, your comments are welcome.

That didn't take long! I'm keen to hear more about the cartridge.

I once asked about German big bores and the .404 (10.75x73) and .500 Jeffery (12.7x70 Schuler) German metric originals, what other German big bores were there? 10.75x68 of course. Hardly got any replies.

Now hearing of all these metric 11 mm plus and minus cartridges.

Need to know more.

Starting with the 11.2x72 Schuler.

Hey Buckstix! You definitely traded up on that deal! Very nice rifle and she came with a dowry too! Dies, cases, an assortment of bullets and even some loaded ammo to boot! And she's in such great condition! The prior owner certainly did take very good care of her. Looks to me like she was meant to be yours all along. She was just waiting for you to show up!

I'm glad you didn't settle for the other rifle. Like they say, 'Good things come to those who wait'.

Have fun with her!

Hello All,
Thanks for the reply.

All in all, I would never have guessed that I would come to be happy that the first deal fell through. However, I'm so much happier with this one, especially since its an original August Schuler, the man that invented the 11.2x72 Schuler cartridge. If anyone has any information about August Schuler and the cartridge, please share.

I hunted with this cartridge and a rifle from Auguste Schüler, and also shot a buffalo with it.

In my personal opinion, this cartridge and the rifles for it are primarily nowadays something for collectors and aficionados. From the same time we have much better cartridges that have stood the test of time and are still being used. That doesn't mean that you cannot hunt with it, just that the rifles are a bit outdated and the cartridge is for different reasons not quite what one would expect.

The cartridge 11,2x72 Schüler is a compromise to fit in an no modified Mauser 98 System, and because of that one have to accept some disadvantages. Another problem is that nowadays there are no more suitable bullets for these cartridges and the old weapons for hunting Big game.

Hello grandveneur,
Thanks for the reply.

Yes, I agree, and fully understand. I wanted a rifle in this caliber mostly for collecting, but still have the possibility of taking it afield.

As a side note. Can anyone tell me what these two marks are that appear on the bottom right of the barrel?

I also bought my rifle only because of interests in the cartridge 11,2x72 Schüler.

I usually hunt DG with completely different cartridges, although the cartridge 500 Schüler also has its place. With a suitable bullet I would have any concerns about hunting DG with the cartridge 11,2x72 Schüler, although the weapon is not exactly state-of-the-art.

The rifle was built in 1923 and intended for export to India. Due to its very good condition, it has probably never seen India, but has seen Africa in the 21st century.

Noone knows for sure. There are several, very similar but differing in detail marks found on Suhl made rifles, most often double stamped as on your’s. Probaably marks of specialized gunsmithes who installed, chambered or headspaced the barrels? You may find a discussion on the German Gun Collectors forum:

GV,

What velocity do you get, 401grs, 11.2x72?

Have you tried resizing bullets down to .440? Eg .458?

The problem with this cartridge is that there is no reliable load data. I also looked at the data from Quick Load, but they all take into account a cartridge length of around 89mm,sometime much more, that does not correspond to the reality. In order to get the cartridge into the magazine, you have to set the bullet much deeper so that the OAL is ultimately only 84.5mm and a lot of powder space is lost. You can clearly see that on many pictures of this cartridge. One cannot therefore rely on the specified velocities for the various load datas.

I load the cartridge with 81gr R 903 or 86gr R 904, more powder R 904 does not go in, with an specified velocity in the last case of around 2050 fps. I didn't measure it, but for many reasons I think that it is much higher, but it won't be much more than 2250 fps or 2300 fps. The recoil is significantly stronger than that of an rifle caliber 10,75x68 and more comparable to that of an rifle caliber 404 Jeffery.

I have never tried to make bullets myself because I don't need the rifle for hunting. I have a few others rifles for that.

Sizing .458's down to .440" would be a daunting task in the first place & require VERY heavy machinery capable of standing much pressure, especially for heavily jacketed ones.

Bumping bullets up would be easier, require expensive dies, but there are not many jacketed .429's of sufficient weight - as in none I am aware of - 300gr. is about it.

Cast is the only way I can see and 2,000fps to perhaps 2,200fps is about perfect maximum. Then, there is the mould problem.?????

Old WW's of the crimp-on variety, made of lead, Antimony with some minor % of arsenic(needed for hardening), cast, then heated in an oven 10F below "slump" temperature, then quenched in cool water will, after a period of 12 hours attain maximum hardness of about brinel 33/34 and can be driven at ANY velocity as long as a good enough lube is used. I have done this with 275gr. .375's and driven them to 2,700fps with 1 1/2" accuracy at 100yards.
The really cool thing about these hardened WW bullets, is they are not brittle.

Wim Degol make bullets for the cartridge 11,2x60, I know that, and may be he makes to order heavy bullets for the cartridge 11,2x72. Nothing else is known to me, or it is new in its catalogue.

One would need SP bullets with strong jackets and also FMJ bullets if one want to hunt DG.

These bullets will then become longer and more powder space will be lost. The cartridge and the weapons for it are just obsolete, that is the problem, but it doesn't matter, it's still a nice collector's item and a part of the history of big game hunting.

Hello DarylS
Thanks for the reply.

No mold problem! I've purchased a couple dozen custom bullet molds from "Accurate Molds". Their catalog lists 84 different molds for .440 dia with weights ranging from 155g up to 585g. I just got another one in the mail today. His delivery is from 3 - 5 weeks and cost is around $100 for aluminum molds, and $115 for brass molds, and $130 for steel molds. I always get the aluminum molds and they work great. You can specify all kinds of variables when you order, and even design your own if you can't find one you want.

Hello grandveneur,
Thanks for the reply.

There is actuall a fair amount of loading data. Pierre van der Walt's book "African Dangerous Game Cartridges" lists 14 different loads for 400g bullets. One load is 80g of IMR3031 for 2380 fps.
Load Data lists 20 different loads for 401g bullets. One load is 85g H4895 for 2450 fps.

I have loaded both of those loads with Woodleigh 400g Soft points to an overall loaded case length of 3.400" without compressing the powder.
This rifle's mag box will accept max overall loaded length of 3.450" max, but I kept the length a bit short to prevent any binding.

I'm surprised at the OAL. I did not think much past 3.380" would fit.
Glad you have data. I'd have thought that H4895's would be a better "fit" (vel. and pressure wise) for this round. Obviously no flies on this one.

My magazine only accepts a cartridge length of 84,5 mm. 3.400" is definitely better, also in terms of bullet seating in the case neck.

Unfortunately, I don't know the book from Pierre van der Walt . I determined my loads myself by using among other things the data from the cartridge 404 Jeffery as a approach.

Hello DarylS - Yes, my mag box is 3.450" max. - I thought that was tight, but I guess not.

Hello grandveneur - 84.5mm = 3.321" - I can easily push the bullets down against the powder in both the loads mentioned above, and get the overall loaded length down to 3.300"

The picture shows where is a other problem when the bullet is set too deep. The bullet is not well held in the neck of the case.

Hello grandveneur,
Thanks for the reply.

Yes, not much neck support with bullets that have a long ogive. Bullets with a smaller ogive with a more cylindrical shape are better. However bullets pushing down into the case isn't a problem because powder fills the case to the base of the bullet.

Hello buckstix,

I also have already done that, the bullet set on the powder, but I don't trust the procedure that much when it comes to hunting dangerous game species.

Lee will make a "factory crimp die" for you. This is "collet" type of die which allows crimping on bullets that do not have crimping grooves in the correct location. I would suspect that monolithic bullets of any diameter would not be able to be crimped but due to bullet diameter with such a collet die, however that won't be a problem with the 11.2.
On ctg. that have mono bullets, they usually have enough grooves to be not a problem for regular crimping.
I my small case .22 varmint rifles, I have found crimping with the Lee die to work wonderfully- same on the .45/70.

Woodleigh bullets caliber .440 unfortunately do not have a crimping groove.

One would need bullets like the type originally intended for the cartridge 10,75x68, a cartridge that also must to be relatively short to fit into an unmodified Mauser 98 system. These bullets have a shape and a crimping groove further ahead that allow to set the bullet deeper without any problems. The cartridge 10,75x68 looks in the reality like in the old catalogues. Unfortunately this is not the case for the cartridge 11,2x72 Schüler.

Again - the Lee "Factory Crimp" die does not need a crimping groove as it is a collet-type die.
You can crimp anywhere on the bullet.

With a cartridge length of around 84mm, you are at the transition from the cylindrical shape of the bullet to the ogival, what is not ideal for crimping.

Back then, Harald Wolf from Hatari Times, a aficionados of the Cartridge 11,2x72 Schüler, had special bullets made for it. Unfortunately, these bullets never went into production.

Beautiful rifle, nice pick up! I love Schüler rifles, and I must say I am not completely familiar with their serial sequencing but here is something interesting. My 8x68 Schüler is s/n 28200, barely past yours, and proofed in 1942, and it’s not an old stock action either, it’s roughly a 1941 Astrawerke made piece. I find this quite curious and interesting!

Since I never intend to hunt dangerous game with this rifle, bullet crimping is not an issue.
Also, I've been swaging .440 dia bullets for my Werndl rifles and I can change the shape of
Woodleigh bullets to provide a longer cylindrical section.

The cylindrical section of the original Woodleigh 400g round nose is 0.400 inches from the base
to where it starts tapering - the cylindrical section of the swaged bullet is 0.850 inches from
the base to where it starts tapering.

Here's a picture of the before ans after.

Hello the mauserkid,
Thanks for the reply.

I would surely think they made more than 42 sporting rifles from 1921 to 1942. Perhaps the numbering
had something to do with caliber. Although the Schuler Co might have been busy making other things
during those years, like their Reform pistol and their teargas pistols. Or perhaps they numbered a
bunch of actions in advance and randomly pulled them from a bin when completing rifles.

Can you post some pictures of your rifle? Is it marked Schuler at the side of the action?

What part of "does not need a cannelure to crimp when using a Lee crimp die" fails to be understood?

I understand the OP saying the ctg. does not need a cannelure due to not hunting with it. Since it is using fairly fast(moderate) burning powders and has a slight shoulder, it might not need a crimp to get the powder burning correctly, as can be trouble in a straight sided case.
I found adding a crimp to my straight sided and small shouldered cases improved accuracy due to improved, more consistent ballistics.

Hello DarylS
Thanks for the reply.

Yes, the Lee Factory Crimp Dies works great even on bullets without a cannelure groove. In my case when shooting any of my Dangerous Game Big Bore rifles, I'm satisfied with 1-1/2" to 2" groups at 50 yds. Also, with my "swage-modified" .440 bullets I can use the conventional Seating die (crimp) to form a slight crimp over the bullets newly formed shoulder.

Some years back, CH4D made a cannelure tool for rolling in cannelures in bullets that either don't have them, or they are in the wrong place. Buddy of mine has one & used it to re-roll cannelures on Speer 275gr. .338" SRN bullets.

I was thinking of mentioning the same thing. These tools were advertised in some of the older Handloader Digest books I have. There was an article in one of the books showing someone using the tool to cannelure bullets and from memory some semi auto pistol cases, to stop bullets being pushed back into the cases during feeding.

Buckstix, I find that serial disparity interesting too, and I would have agreed with the setting aside of an action, if it was an old action, however this receiver is roughly a 1940/41 Astrawerke made piece. It is not marked on the sidewall as yours is, but rather on the barrel in 2 or 3 places IIRC, including the intertwined “ASS” trademark. It has some definite similarities to your rifle, for one, the mag well is cut out of the aft end completely, like yours is, to fit the 8x68. In general it conforms to the typical 1940’s style from Schüler and is fit with a Röchling barrel.


Looking forward to your progress with the 11.2 that’s another dream gun! Keep the updates coming please.

Hello All,
Thanks for the reply.

After doing some diligent research, I was able to acquire a copy of the original ad from when this rifle was first offered for sale many years ago.

Gentlemen,

the company of Mr. Wim Degol in Belgique produces bullets in dia. .440" for the 11,15x60 (330grs, not intended for the Mauser M71!) and the 11,2x72 Schüler (401grs, FMJRN and RNSP).

I was loading ammunition for the rifle Mr. Harald Wolf manufactured for his report in the Hatari Times.
Powders used were Rottweil R904 and Rottweil R907, conservative reloads produced velocities approaching 700 m/s // 2300fps with the 401 grs bullets and Bertram cases.

Precision was good, taking into account that only a Zeiss 1,5-6 power scope was mounted. The shooter was the limiting factor...

best regards
Rolf

Rolf,
What is the case dimensionally compared to say the .404Jeffery, can it be made from any other case?
The loads I have for my .404 are just a bit more than 2300 fps for the 400gnSP so it is easily comparable performance wise.
Rottweil make very good powders - its a shame, as far as I know they are unavailable here in Australia

Interesting question; the .404 Jeffery is a bit longer than the 11.2x72 so that would be no issue.
I just measured both cases base diameter: Norma .404 Jeffery is ~.540" and Bertram 11.2x72 is ~.533" (rebated rim of course).

Thus it seems that, depending upon how generous the chamber might be, that the .404 could be swaged down and with a little lathe work on base & rim it could be made to work just fine?

Hello 93x64mm,

According to the Handloader's Manual of Cartridge Conversions, you can make 11.2x72 cases from 404J brass. Case capacity in water is virtually identical. Also some old Bertram brass measured .441. The new stuff measures .436. Spinning a 404J case in a lathe and touching the head with a file will easily remove a couple thousands from the head dia. Then simply cut a new rebated head with extractor groove.

Ian McFarlane created the 440 McFarlan about 20 years ago using the 404 Jeffery case. I never got around to having a bolt made for the 404.

Harald Wolf in Hatari Times writes about the conversion 404 Jeffery cases in 11,2x72 cases, noted however, that the process would be very difficult. Nevertheless, you might have to take a critical look at that. Harald Wolf found some things very difficult for non-professionals, including reloading 500 Jeffery cartridges for example.

Thanks for that grandveneur - handy to know
I read somewhere that Jack Lott used .404J brass for the .425WR & just changed to an opened up bolt rather than use the .425WR brass if it wasn't available.
I think it was in his Big Bore magazine article.
Would certainly apply for this 11.2 as well

The existing bolt could be replaced (save the original) with a bolt modified for the 404 Jeffery case and then shoot standard rimless instead of the rebated rimmed 11.2x72 ammo. I think that's why Ian created the 440 McFarlan. Then run the 404 case through a 11.2x72 resize die and fire form.

Got it in one jgrabow!
No Buckstixs, I was only relaying a note I read on Page 78 below - it refers to the .425WR, but in this case if the 11.2 can be made from the same basic .404 case, then it is a viable option to keep your rifle going

Hello 93x64mm.

Nice copy of that magazine. I own the rifle shown on page 80 and at the bottom of page 83. Its a Custom Mauser in .458 Winchester Magnum cal. He built the rifle for Howard French, the Executive Editor of this magazine. (ref: page 2)
