333

I got some pure lead bullets from a guy on another site.
They are 720 grains cast from a modified 600 NE mold (originally 900 grain but shortened at the base)
When drilled with 3/8" bit (HP) they end up being 500 ~ 550 depending on depth.
Have not had a chance to try them yet.
I need to put lube in the grooves, but have none.

Nitro

PS: They are 0.622".
