Can anyone direct me to a formula or program that calculates the necessary twist rate to stabilize various bullets?
I am interested in trying the 75gr A-Max in a 22-250 AI and also the 208gr, or the rumoured new 225gr A-Max, in the new 300 Norma Mag (improved).
I want to be sure to use barrels with twist rates fast enough to stabilize these bullets at sea level, but I don't want to have overly fast twist barrels as I may try some lighter bullets as well.
