OK
I cast up some 500 gr and 300gr bullets today and my Saeco Hardness tester came in.

I tested the 500 gr with a hardness of 5(aprox. Brinell of 8) and the 300gr with a hardness of 7(aprox. brinell of 11?).

I cast them at the same time out of the same pot and air cooled.

My question is are these to hard to shoot out of a Turnbull 45-90.
and should I mix in some true pure lead to soften them up.
