Old rifle cartridge????

[Detector mom]

Hi. Found in woods in northern NJ.

Some sort of ammo?

Kind of looks like a CO2 cartridge.
That's rusty steel (iron), rifle cartridges are made of brass.

That would be my guess as well.

Ok, don't laugh, but: What's a CO2 cartridge?

 

[GaRebel1861]

They have several uses but, they are commonly used in pellet guns.

Could be a Whippet cartridge too. They are more fun being filled with nitrous oxide (laughing gas) than CO2 ones.

Also used in BB guns.
