[QUOTE="Michael Eichele, post: 356497, member: 1007"] My guess is niether. If high BC had anything to do with surviving it the 300 would have a better chance. If higher than average Sg and shorter bullet had anything to do with it the 250 would. However, based on past experience using a 1.9 stability factor with a shorter than average bullet, they still destabilized at the transonic range. So either it was over spinning them that did it or it was other factors. Regardless, a very high Sg didnt save it. However, it would be very interesting to see if one or the other survived. Best case, they both do. Worst case niether do. Better yet, one or the other. This would give us an indication as to whether it was a higher BC or a higher Sg that did the trick as using your example would show that. The 250 would have a conciderably higher Sg which if it wouldnt make it would show that too high an Sg would cause destabilization. If it survived it and the 300 didnt it would show that a lower Sg regardless of BC isnt the answer where the higher Sg is the answer. If only I had a place to shoot 2000 yards :( [/QUOTE]
