Does bullet stability drop of with velocity??

[QUOTE="rscott5028, post: 515697, member: 24624"] My understanding is that once the bullet reaches gyroscopic stability, it stays that way pretty much until impact except for the transonic range which is really a separate issue. If it's unstable to begin with it probably won't get much less so. But, it's going to seem like it over long distances where you need better accuracy for a clean kill. Depending on your bullet, then your impact velocity should ideally be above 1800 fps for good terminal performance on game which is well above transonic. ...perhaps 2000fps or more for the Scirrocco? Gyroscopic stability is one factor affecting accuracy. You can sometimes find a load that matches the harmonics of your rifle and it will provide sufficient accuracy with a marginally stabilized bullet. You would just have to try it. I've wasted a lot of time trying to make slow twist rifles shoot well with longer bullets. Life is too short. I prefer to go by the calculator and focus on one that's a mathematical good fit. -- richard [/QUOTE]
