OK, so I'm going to sound really dumb here, but can someone please explain the barrel twist rate/boolit diameter/boolit length/boolit weight/velocity ratio?
By this I mean how would one take into consideration the potential use of boolit "A" of weight "B" and diameter "C" and calculate a minimum and maximum usable velocity "D" and "E" taking into consideration the one constant, which is barrel twist rate "F"? Or does rotational spin "G" come into play also?
It thus far has escaped my mind how it is calculated.
I have seen the Greenhill formula, but it does not seem to apply in all cases. Or are the exceptions to the rule the proverbial "proof in the pudding"?
