[QUOTE="straightshooter, post: 474666, member: 9775"] robbobsam, read KRP's reply. Don't worry about stability calculations. Shoot to verify, even the 1250fps rule does not always apply. Search the net for "shooting a 223 to a mile." That blows the myth of 1250fps out of the water. Some bullet designs will destabilize when they go subsonic, but that is a general rule, not the golden rule. If you have the right set up you can shoot accurately a very long way. Every rifle bullet combination is unique so you have to shoot to verify. I shot a 1-14" twist 223 with a 75grn bullet that was keyholing at 50 yards. At that distance it was going way faster than 1250fps. I then shot that same bullet in a 1-9" twist and was grouping at 1050 yards no problem.
