View Full Version : Weird Cartridge

January 14, 2007, 03:06 PM
This cartridge is just over 1 1/2 inches long, the I.D. at the neck is approx. 7.35mm & has a very unsual rim. Stamped on the head, if I am reading it correctly, is RVA8-157 MK2A4 3-54. The brass is very heavy, any ideas what this is?

Looks like an artillery or naval gun shell primer.

quite possibly. I once found a round that was about the size of a 12ga, with a slight neck. It was filled with a very coarse powder. Was told it was a primer for artillery using bagged charges, not cased ammo. Yours could very well be something similar. With all the different nations guns over the last century and a half, it might be rather difficult to ID it exactly.

The M2A4 is for use in the Mk 114 series howizters only.

The tube contained 19 grains of coarse black powder.
