SEALED CYLINDER

[steelheadwill]

Greetings T-net Sleuths,
Found this in mud near naval base,
2-3/4" X 3/4", feels hollow, reads as brass,
The only idea I can come up with is a carpetbomb submunition, (save it for Independence Day 2011)
Anyone got other Ideas ?
Best To all & HH, Herbie.

Do you have a bunker in your back yard?

That round end with what looks like a crimped on ball (projectile?) warns of something bad (possibly).
