Hardpan Curmudgeon SASS #8967 Posted November 6, 2015 Posted November 6, 2015 Not that big, but... they find 100 unexploded devices a DAY??? Uh... I'd seriously consider moving.
Badger Mountain Charlie SASS #43172 Posted November 6, 2015 Posted November 6, 2015 A 10% failure of ordnance? Is that normal?
Sedalia Dave Posted November 6, 2015 Posted November 6, 2015 It is in amazingly good shape for something that was fired from a rifled bore and impacted the ground at a significant velocity.
Utah Bob #35998 Posted November 6, 2015 Posted November 6, 2015 It is in amazingly good shape for something that was fired from a rifled bore and impacted the ground at a significant velocity. I believe the brass rifling band is gone. That's what catches the grooves in the barrel of a gun that size. So there wouldnt be striations on the actual shell like a pistol bullet. If it hit soft groundn there wouldn'y be much danage to the shell. Tough steel.

Yep...here is one with the driving band still on:
Marshal Mo Hare, SASS #45984 Posted November 6, 2015 Posted November 6, 2015 The rotating band (copper alloy part near the base) is what gets grooves from the riflling. It appears to have disappeared. Perhaps it gets so damaged from firing that it comes off during flight.
Noz Posted November 6, 2015 Posted November 6, 2015 The rotating bands frequently come off of the larger artillery shells.
Guest Grass Range #51406 Posted November 6, 2015 Posted November 6, 2015 Looks more like the projectile instead of a shell. I don't know anything about navel gunnery but I think this is a separate loading round so there is no shell or canister if you will

Subdeacon Joe Posted November 6, 2015 Author Posted November 6, 2015 The projectile is commonly called a shell in big guns. Because it is an exploding shell as opposed to solid shot. Or canister.
Utah Bob #35998 Posted November 6, 2015 Posted November 6, 2015 Because it is an exploding shell as opposed to solid shot. Or canister. Zackly.
Grouchy Greg, SASS#71981 Posted November 6, 2015 Posted November 6, 2015 Me neither. The only things I've found in my garden are arrowheads and an old twisted mule shoe.
Utah Bob #35998 Posted November 6, 2015 Posted November 6, 2015 Lots of mud in Nam. Not surprised it's not even dented.
