[QUOTE="Mikecr, post: 1911388, member: 1521"] It won't shoot worse as stability goes up. 1.0 is stable, 1.3 is marginal (which is fine), 1.5 is fully stable, higher than 1.5 is still fully stable (and no more). Keep in mind that gyroscopic stability rises as the bullet travels down range. This doesn't bail us out of bad stability on muzzle release, but it proves that high to very high Sg doesn't hurt us. So your calculated Sg at muzzle release is 1.39. Then by 250yds that bullet's Sg will be ~1.71, right there where you're at. By 500yds, that bullet's Sg would be ~2.15. It isn't hurting you [/QUOTE]
