Maybe that's why some rounds do better in a gun than others.
What I've done in the past is call the manufacturer and ask them what bullet weight range they designed the twist for optimal performance. You will be passed around a few times but someone will eventually be able to answer the question and it beats trying to calculate it yourself and always wonder if you did it right. When I called Smith and Wesson for my 7mm Rem Mag they gave me a pretty wide range. (130 to 175 gr) I settled on hand rolling 150 gr partitions for all my needs.
