A while back a friend found this, what I'm guessing is a cartridge of some kind, on one of trails up around Cherry Lake in Tuolumne. We have always just speculated at what it may be. It is time to tap your knowledgable minds and figure this out once and for all.

I don't know if it helps but that is a mini mag light it is next to and a regular size beer mug in the back on the right.Comment

It looks like a 20mm and it might have something in it other than lead
I just measured the bell on a mini mag, it was 25mm and its hard to tell if your expended round is wider or narrower than that.Last edited by kurac; 09-27-2010, 8:07 AM.www.culinagrips.com

I have one just like it, minus the nose cone. It measures 37mm and was found sitting on a rock in the area Patton "played" war games in the early forties before being sent to the European theater. The Grant/ Lee and Stuart tanks of the time carried the gun in a turret and there was an AT gun as well, to bad they were obsolete from the get go of Dec '41.Comment

Thank you guys. This is interesting. It is in fact the same diameter as the Mini Mag.Comment

Meinbruder can you send me a pic of your casing I would be interested in seeing another one. I, for the life of me, cannot find a picture of one like it. Thanks.Comment

What may or may not be inside the projectile. Im sorry if I'm asking too much but I'm just happy to be learning this stuff. What are the "ridges" around the bottom for. And for the most intriguing question. Why would this be up by a lake outside Tuolumne City?Comment

The ridges are rifling marks. Why was it there? Could have been fired during a training and traveled miles before coming to contact with the earth, could have been carried up there in some kids pocket and lost, could have been ?????
I'm far from an ordnace expert so, I won't even speculate what might or might not be inside. But, if ANYTHING other than metals are inside it, it is probably not safe to have and illegal in CA.NRA Certified Pistol, Rifle, Shotgun and Metallic Cartridge Reloading Instructor

The ridges around the bottom is a "Driving Band", which is made out of soft metal,usually copper,brass, etc. This is where the rifling of the cannon barrel contacts the driving band and spins the shell when traveling down the barrel. You see the rest of the shell is made of steel. The driving band prevents steel on steel contact.
The shell is likely an inert practice shell,but unless you have an old ordinance expert look at it and confirm it, it's prudent not to fool with it.Last edited by FLIGHT762; 09-27-2010, 4:34 PM.Comment
