Buried deep in my stash I found this old brass. The unmarked cases are berdan primed. The UMC cases are boxer. Im not sure what they are. Except for length, they are about the same. What do you think?
Length: umarked are 2.250", UMC are 2.300"
Rim: .635"
Rim thickness: .085"
Base: .518"
Shoulder: .515"
Neck: .463"
the unfired is a 43 Mauser. The other I would guess is a 44-77. A 43 Spanish should be a smaller neck.
I believe the cartridge Head stamped UMC/USA is 11mm Mannlicher made by Remington, Metric 11.15x58R Austrian Werndl. The other has the remington ringed base , 44/77 or blown out 11mm Mannlicher
Unfired looks like 11mm Mauser;
fired case looks like 11.15mm Spanish--the case heads are too small for 11mm Mannlicher/Werndl, and case neck on the Spanish is larger than the standard cartridge dimension because it has been fired.
I vote 43 Spanish, because of the rim diameter. The others mentioned above have a smaller rim.
Hmmm, quite few possibilities....:veryconfu
Gents, we went through this over on the ASSRA Forum too ... 3 pages long

BTW ... boxer primers wanting to make 44-77’s out of them
Thanks fellas, I appreciate your thoughts.
ndnchf ... for staters if you had the right reference you would have determined what caliber brass you had:Quote:
Yes I have done some research and have some references,
Handloader Manual of Cartridge Conversion that will give you all the information you need to determine whether the cases are 43 Mauser - 43 Spanish or 44-77 ... down load it for free ... https://www.pdfdrive.com/the-handloa...165406074.html or buy the paper copy
* This manual will tell you all you need to know about the 3 calibers, case, bullet diameter that you questioned and loading data ... plus you then know what brass you have and no questions to asked
* early on ASSRA, determined were not 44-77 ... so stop
You mentioned you had several Rolling Blocks and wanted a 44-77, SO...
* Pull a barrel of one and order a 44-77 ;
* Put sights on it
* Take the RB tread measurements cut them on the new barrel
* Order 50 new 44-77 brass from either Roberson Cartridge Co or Rocky Mountain Cartridge Co - they both are lathe turned
* Buy the 44-77 bullets or cast them and lube them
* Order a set of dies
* Reassemble the new barrel to the RB action
* Rent a chamber reamer
* You should be able to modify the extractor or order a new one from http://www.rollingblockparts.com/
* Load the cases with the data from Cartrige Conversions or other source
DONE - not 4 pages of questions
John,
Sorry I don't have every reference, but I will download it - thanks. I never said or implied that I wanted to build a rifle. In fact, I bought an original #1 sporting rifle. While I appreciate the guidance and suggestions here and on the ASSRA forum, your ridicule and mean spirited attitude are uncalled for. I will end this discussion here and will also end the ASSRA discussion.
ndnchf - sorry that got off track a bit. the first case uses the Mauser "A" base. There's only 4 that use that, 11mm Mauser, 11mm Werndl or Mannlicher, 11 Gras and 11 mm Murrata. UMC is a commercial supplier and I know they made ammo for 11mm Mauser and 11mm Mannlicher (Werndl). I don't believe they made any for Gras and quit sure not for the Murrata. You posted numbers rule out the Werndl (Mannlicher) so it's an 11mm Mauser. The other is a guess, probably 43 Spanish as it's pretty common. The numbers aren't conclusive as they wonder a bit from printed sources, such as Cartridges of the World and others. Any of this stuff is 140 years old. There is a guy trying to sell a collection of Mauser 11mm cases on gunbroker. It looks like there were dozens of manufacturing plants. I know the barrels of the 71/84 were gauged and stamped with bore size before rifling, generally plus or minus one half a millimeter ( appx 0.020 inch) so some variation in brass from posted reference is to be expected. hope that helps.
Certainly not the Werndl. The neck looks too short to be Mauser. Barnes mentions a Mauser revival by Krieghoff in the 1920s. Could it be that? Reformed from brass that was made for the original Mauser?
I find it very hard to believe that Germans would allow that much bore variance!
I see I missed a decimal place in my previous post, not 0.02 but 0.002. The 71/84's were gauged prior to rifling or leaving the plant. The bore size is stamped on the left side. Generally 11.00, 11.05, or 10.95 or something similar. I'd have to dig out a book or two to really be correct. Point is they did vary by a substantial amount; 0.05 mm = 0.0019 inches or nearly 2 thousands. We see that in WWll production. With black rifle, the bullet obdurates and it makes no difference. Good eye uscra112.
