Ran across a DR in this caliber on Guns International. I had never heard of this chambering, Guess I have been living under a rock. Went to "look it up" and can find nothing about it.

Can anyone tell me about this cartridge?

Thanks,

I see from the description of the rifle, that the cartridge is a black powder one, or at least that it is proofed for black powder. This seems strange, since the only proof sign visible is on the left side of the left barrel, which reads St.m.G, and stands for Starkmantelgeschoss, or jacketed bullet, not one usually associated with black powder cartridges. A photograph of the bottom of the barrels might shed more light on the situation.

Gun dealers as a group are not known for their mental acuity in identifying foreign made weapons.

There is a description of a 10.75X65R Collath in Cartridges of the World, 4th Edition, page 277, but that seems unlikely, and a 10.75RX58 Russian Berdan in the same work, page 211, but neither of them seem a likely choice for a German hunting rifle not made by Collath. Otherwise, I can find no rimmed 10.75 cartridges.

There also appears to be a "crown N" proof to the left of the St.m.g. which if the letter is an "N" it would mean proofed for smokeless powder. Looks more clearly like an "N" a few picture further on.

Dug around a little more. Any possibility it could be a .43 Mauser aka 11x60R? Beats me.

Has some chips out of the horn trigger guard. Wonder what this DR is really worth? Maybe what they are asking.

The Swiss use the 10.3x60R as a hunting round based on their weird rule of bullets over 40 caliber for hunting in most Cantons.

It is the common 11mm Mauser; remember, many/most cartridge designations use the bore diameter rather than the groove /bullet diameter in their designation. So, 10.75 would be right. And it was obviously made in the Nitro era, and so proofed.

Claw bases too; this rifle is under priced and if I had any money, I would buy it today.
Stock might be shrunk from the frame on the left side; could be the picture.....

Thanks. I was trying to remember that whole bore vs groove thing. Makes sense now.

See Dixons "European sporting cartridges" pg 69 & 139. 10.75x60R Grundig
"This calibre does not appear in the RWS/Utendoerffer c1908 catalog but does appear in the 1911 Alfa catalog being manufactured by Utendoerffer. DWM listed this calibre as a 10.75x60R for H. Leue of Berlin (case #495A >1905) & Roth also listed this calibre (#759 c1907), but specimans by these two companies are not known. Also listed by Gecado into the 1930s)
DWM book lists case 495A as "Puerschbuechse Kal 10.75mm G.C. Dornhem, Lippstadt"

Guess anything is possible. A chamber cast would put it to rest. I may have gotten lucky though. Don't have to explain to the wife dumping $4K on an "old rifle." I am #2 in line.

That thing's a stunner and Kirby's a first class seller (IMHO). Worth every penny but would take a while to work up a load.

I recommend putting the question on germanguns.com. There are a few people on there with encyclopedic knowledge about these things.

A thread on this cartridge over on NE forums. I posted some info on that thread.

What's the correct name of Dixon's book? Is it still available as used or new? I believe I need to own one if possible.
