WebJun 8, 2024 · The idea that you might "spin a bullet too fast to stabilize it" is an old myth. Faster spin improves gyroscopic stability (up to the point that you spin the bullet to pieces, which is far less common now than in days of yore). If you want to dip your toe into the math, read pp. 157-166 (the first part of Chapter 10: "Bullet Stability") of ... WebAug 15, 2013 · This paper describes the effects on aerodynamic drag of rifle bullets as the gyroscopic stability is lowered from 1.3 to 1.0. It is well known that a bullet can tumble for stability less than 1.0.

WebSG is the specific gravity, or the measure of gyroscopic stability applied to the bullet by spin. Mathematically SG is the ratio of the stabilizing influences of rotating mass, vs. the de-stabilizing effects of aerodynamics. If this ratio is greater than 1.000, it means the bullet has more stabilizing influence than de-stabilizing influence, so ...
