Can you identify this projectile?

Late model Shermans had the 17-pdr gun. It used the same 76.2mm ammo as the Soviet AT gun. Projos were boat-tailed because the MV was just a tad high: 2750 ft-sec, same as a .30-`06, just a tiny tad bigger.

I got 5 bucks sez this critter is INERT and always has been. No point getting all bent out of shape.

Take a look at Ian Hogg`s ammunition book: this thing is a SHOT, pure and simple.

I prefer ammunition to people a lot of the time. Ammunition only goes off when there is a REASON.

Has nobody ever thought that, in order to have an explosion, you gotta have something that explodes! That means that you have to have somewhere to PUT the stuff, a significant quantity of it, too, and there aint nowhere here to do that. Base fuses screw in but they are BIG, much bigger than the tiddly little trace element that was in this one and burned out before most of us were born.

This is a GREAT old artifact and a fun souvenir. It`s about as dangerous as a 13.5-pound anvil.

Enjoy!

You lost your money the moment you posted. As the projectile included a tracer element, which appears to have been consumed on firing, though it is most likely now it was not always INERT.
 
Can the OP please provide an over-all length of the projectile and a better photo of the bottom of the projo which clearly shows if the tracer was threaded or press fit. If possible please put a set of calipers to two directly opposing striations on one of the driving bands.

Is the weight given accurate?

I should put up a little disclaimer. As we're dealing with photos without scale over the internet and the inability to inspect the projo in person for markings and measurements, all information provided is purely for academic enjoyment. Viewer and handler discretion is advised :)
 
I am using 6" Mitutoyo calipers. The depth of the jaws isn't quite enough to be certain that I am catching two opposite high spots on the driving bands. I measure just shy of 78mm at the widest.
 
didn't I tell you

If it goes boom (or not in this case) petrock is the man to ask. Thanks for the help buddy I appreciate it.
