[QUOTE="Trickymissfit, post: 989516, member: 25383"] many years back, I'd have said a 60 grain bullet was a 60 grain bullet as long as the diameter was the same. I got a training lecture from the guys out of Fairland one day, and things almost changed instantly. It was a factor of ballistic coefficients to the twist rate and not much more. From there we can sort of tune the load by bullet location and chamber pressures (powders and primers). A lot of times it's only a couple tenths of a grain of powder or five thousandths in seating depth. gary [/QUOTE]
