[QUOTE="Michael Eichele, post: 273062, member: 1007"] Very well put BH. As well as very true. I might add that many shooters still use the greenhill formula for twist calculations. Today there are so many more ways to calculate twist taking into concideration ALL the variables that go into finding optimum twist. There is much more to it than just bullet length and bore diameter which is primarily what GH was founded on using only two velocity ranges. No need to restrict ourselves today with all the knowledge and technology we have at our disposal. [/QUOTE]
