11.15X60R M71/84 Mauser

Right cartridge in 1st picture has been correctly identified as 11.15X60R M71/84 Mauser. Further down are 2 pictures which I am asking if this is a 11.15X60R made by UMC? Measurements are same as 1st pic 11.5X60R except 3.03 cartridge length.
Bear with me as I learn how to use the editing functions.

Need help to clear these 2 from my desk.
Left hs W-W SUPER 30-40 KRAG. bullet .429, 2.05 cartridge length, 1.75 case length, .536 rim diameter (wildcat?)
Right hs S 86 * 8, bullet .457, 2.83 cartridge length, 2.35 case length, .586 rim diameter ( beveled rim & large brass primer matches 2 other types of Spanish 11.15 which I have. But rim is smaller?)

I believe someone was trying to make a 45-90 Win. round as shown as the left cartridge…Pete.

Please check the 36 on the right cartridge headstamp.

As Dan pointed out check the " 36 " which in fact may be " 86 ".


Attached as requested. Believe you & Brian are correct as the loops appear to continue

With this headstamp the original case was a M71/84 Mauser by Spandau 1886 (11,15x60R), but reloaded…

Appreciate it.

The one on the left reminds me of a .445 Super Mag. All Super Mag cartridge brass cases were 1.620" long. Before commercial brass was made, people used .30-40 Krag brass as a basic brass. Even though this bullet diameter is .457", it could be an example of the never-produced .455 Super Mag. Where did you pick this up?

It was mixed in with singles which I purchased from a long-time collector.

Appreciate the info.

You helped me identify a M71/84 Mauser (11.15X60Rl) last week. I have come across another cartridge with same measurements except 3.03 cartridge length? Did UMC make this item as headstamp reads U.M.C. U.S.A.

Pastammo, please be so nice to address the titles of your postings more precise as a reader hardly will know what the thread is about amongst all the others. And threads with identical names are even more confusing.


Will do

Great, thanks! Means you can rename your threads easily here.
