[QUOTE="Cheezie, post: 2289287, member: 56093"] Actually, stability is a parameter that can vary either way from neutral. Stability is the property that describes a bullet’s response to a perturbation perpendicular to its flight path. If disturbed, the bullet will wobble ever so slightly and recover (positive stability) or it will diverge in the direction of the perturbation (negative stability.) If stability is neutral, the stability parameter is 1.0; less than 1.0 is negative stability, greater than 1.0 is positive stability. Most bullet people advise using a barrel twist rate for a particular bullet and velocity that results in a stability parameter of at least 1.3, and 2.0 or 2.5 is better (more stable.) The higher the stability the more resistant the bullet is to disturbances to its flight path. [/QUOTE]
