Odd Lead Projectile


I found this odd shaped lead projectile. It reminds me of some type of cutter shape.
The bevels look even so maybe not home-made?
What cartridge would it fit with this diameter?

Weight 167.6 grains. 10.8mm (0.425") Diameter. 15.8mm (0.627") Long.

Any comments are welcome.


I forgot the photos.
