Which metal?
My store has the following leagues:

-CuZn39Pb3 (brass)
-Cu-ETP (copper)
-CuSn7Pb6Zn4 (bronze)

This for making a new bullet in .413 for caliber 10,3x60r bullet gr 240 approx.

Velocity final charge I think
850 m/s (2788 ft/s), barrel lenght 65 cm.

CuZn39Pb3, also called free machining brass, has the best machining characteristics.

10,3x60r,
Don't now for sure. We use it as it is (half hard condition, 120 Brinell) for making shotgun slugs that are enclosed in a sabot.
Try to anneal at 60-70 Brinell to see what happens.
