At the same relative pressure the Berger shot 30-45 fps faster. At velocities below 2900 fps twist rates of 1-9, 1-10, 1-11 shot well. At velocities above 2900 fps 1-10 and 1-11 shot well, however the 1-9 twist was just plain nasty. In the 1-9 twist test rifle that shot so poorly at 3003 fps the powder charge was reduced to a level of just under 2900 fps and shot the best groups of the day. It is quite clear that you can twist this bullet too fast at a certain velocity threshold. If I was building a rifle capable of driving the bullet over 3000 I would not go with a faster twist than 1-10 and would lean toward a 1-11 twist. A note on transonic / super sonic range and twists - for sure the 1-11 will not shoot worth a **** when the bullet go near or into the transonic range, it is possible that no amount of twist will help this. The positive note is that if you drive the bullet 3000 fps that the transonic boundry is around 2700 yards given reasonable atmospheric conditions. I believe that this bullet has huge potential and I am looking forward to serious long range testing in the future with it. [/QUOTE]
