[QUOTE="RockyMtnMT, post: 1452068, member: 7999"] From our testing for terminal performance a 1.5sg is the target for good terminal performance. When it comes to terminal performance it is more about the rpm's than the sg. The higher the rpm's the better a bullet will perform on impact. After all of our testing I no longer use elevation when calculating bullet stability for hunting applications. Elevation helps for external ballistics but not for terminal performance. After impact testing in media more bullets than I can remember and being involved in over 100 game animals taken and seeing results from varying bullets and stability factors, I consider 2.0sg to be ideal for hunting and 1.5sg to be the lowest to expect reliable bullet performance. Again I calculate for hunting at sea level. If target shooting, enough stability to fly well is all that is needed. Depending on the bullet a 1.2sg can produce great accuracy. Steve [/QUOTE]
