I got a bunch of boolits in a trade some yr's back..
Can anyone help me identify the mold used for this one?

Weight 207 grains of unknown alloy ( rather hard?, prolly water cooled WW)
Thanks.

Yes, thanks!
Ive only seen lyman's catalog pic and it seems to have a rounded WC edge.. But now when I found actual pic's of the cast boolit I recognize it!
