What is the red goop in the primer pocket and on the rim where the extractor groove should be?
No cartridge I know uses 0.030" thick brass at neck. That is not a "design" on head, it is brass spall over concentric-circle stamp/forming marks, (not milling/turning marks).
Cut-down rifle case? Maybe. However, while hard to see the mouth appears at some point had a very heavy crimp. NO cartridge comes close to matching that head and at-mouth diameter and length, so what die could have done the crimp?
Hard to see, case appears to have heavy black powder fouling.
My guess: ordinance electric or percussion primer, or artillery fuse igniter. The .452" inside mouth diameter is pure coincidence, or someone tweeked brass after being fired.
