Bought this for a few dollars on a whim and is far outside my normal interest. Can anyone possibly ID what this could be from? Its made of solid Lead and was dug up in the UK by a metal detector on a beach, hence the crusted on corrosion.
-Rifling grooves: 7 (as best I can tell)
-.50BMG AP projectile for scale in the last photo
It’s got a half-dome shape pressed into the bottom and has a groove approximately 12mm from the bottom of the projectile. It’s slightly lopsided on the bottom as well so doesn’t sit straight upright.
Thank you and best regards,
