This I do find fascinating. I researched this a bit and find the engineering of it all entertaining. Gives me great respect for those who design barrels.
Thank you for pointing me toward the Greenhill Formula
edit: A cursory search leads to heavy debates between this formula and the Miller Twist Rule. Any books you recommend? What about Bryan Litz - Applied Ballistics for Long Range Shooting?
Brian Litz is probably THE expert in small arms ballistics.
But the bottom line is, the formula's are predictive, but not absolute. Same make and model rifle, with the same twist rate, one will work with XX gr bullets, the other will not work with that same load and needs a lighter bullet.
There is still a lot of art out there.
