As has been stated several times on this thread, sizing is more important than alloy hardness.
So, size does matter? Or, the hardness?
28,
What I was trying to convey in my original post was more related to accuracy and the ability to shoot cast bullets without leading. IME, a cast bullet does not need to be "hard" to achieve either of those goals. That said, one can shoot 10 to 11 BHN bullets as well as much harder bullets without leading problems IF they are sized right in relation to throat/bore diameter.
Therefore, size does matter, but as has been said, in some applications hardness also matters. (Still talking about cast bullets here) Grin!
