In the Miller expression, desired stability for optimum accuracy is expressed as best in the 1.4 – 2.0 range. Berger at 1.5 are I suppose just being conservative.
That Berger understand these principles, and make fine bullets is unquestioned. So why do they not make projectiles in their hunting range, suited to the commonly available commercial twist rate hunting barrels? The 30 cal in either 12 or 10 ” twist is a classic example.
Applying this formula to the Berger hunting bullets in common hunting rifles and conditions, produces numbers that are either above or below these figures for a large number of common hunting rifle/cartridge combinations. This question was asked of Berger’s technical assistance line some weeks ago.
I have yet to receive any response.
Perhaps accurateshooter can help us here.
