What does it matter? A roundball is a 150 to 175 yard projectile [unless we are talking cannons].
You would have to test your ball's drop at 75; 100; 125; 150; 175; & 200 yards to KNOW what it is. Because what exact alloy and size [not to mention shape] mold you use would affect it.
Checking actual bullet drop, in your gun, at known ranges is the only real way to know these things.
If your wondering about ball vs connical the difference in velocity more or less balences out the difference in BC.
