[QUOTE="RockyMtnMT, post: 2668475, member: 7999"] Hey Kirby, we have run into the same thing but without a tip of any kind. I have a sneaking feeling you are running into a dynamic stability issue that shows up when higher velocity is hit. The longer for caliber a bullet gets the more likely you are too run into an upper speed limit that causes them to want to swap ends. When we ran into it was when we did the 6.5 Ultracat running a bullet that was pushing 2" long in a 6" twist. On paper was pushing near 2.0 sg. Rifle was shooting solid sub 1" at 200y until we got 3200 fps or so and at 3300 fps had sideways impacts at 200y. [/QUOTE]
