[QUOTE="RockyMtnMT, post: 2410592, member: 7999"] Here is what we have learned. The elevation helps with ballistic stability. I doesn't seem to help with terminal stability. This seems to be much more dependent on rpm's. Also the longer the bullets are for caliber the more critical there stability gets. So when we calculate minimum required twist we do so at standard atmosphere at sea level showing a 1.5 sg. If we stay pretty hard with this then there is very little issue with on game performance. This bullet is starting to push the threshold of bullet length to caliber ratio. The point that everything just comes undone is about 6 times caliber in length. This bullet is only .082" from that ratio. [/QUOTE]
