Lol I appreciate the concern, but when I said "spent primer", I was also implying that when the primer was struck it ignited the propellant inside of the large shell and fired whatever projectile was lodged in there a long time ago. I don't believe it to be brass, more likely steel but I suppose I can look into that a bit further. My tape measure is at work, but by eye I'd say it's about 30" high, with a diameter of roughly 6 to 7 inches around....definitely on the large side. I'm on an I phone but I'll try to get some pictures up here ASAP, along with the sword and canteen I dug up in the same area as the shell. Oh and Willie, I found all of these items and more on a large property in Monroe Connecticut. Thanks guys
