[QUOTE="LouBoyd, post: 636701, member: 9253"] Stability is also dependent on velocity and air density. The only reasonable way to determine if a given bullet will work in your rifle with your loads is to shoot in the highest air density conditions (coldest and lowest elevation) you expect to encounter. I live and shoot at a mile elevation in Arizona. Published twist recommendations are are useless. You can try calculating stability with one of the many published methods including McGyro, but shooting tests are more trustworthy. If I took my rifles to a cold place near sea level they would shoot very poorly. In that unlikely event I'd have to change bullets and loads. [/QUOTE]
