Sorry, Chuck. Never have had the need to try any. Looking at Rotometals data #7s measure .010", same as an American lead #7. Given the difference in density, I'd guess they would fall somewhere between lead 7 1/2s and 8s, in energy. ????

Sorry you have to resort to this, man. I like Bi, and reload it, but would hate to have to for quail or doves.

All my best, SRH


May God bless America and those who defend her.
