coefficiency

We shall again reply here by figures, while remarking that the adhesion of locomotives increases with the speed, according to laws still unknown or imperfectly understood, and that consequently for extreme speeds, ignorance of the value of the coefficiency of adhesion f in the formula

But there is one aspect of aerodynamic drag that does have a significant measurable effect on bullet trajectory, and that is the ballistic coefficiency of the bullet.

I have discovered over the last 6 months what millions of shooters in this country have long known: that an accurate, well-aimed, modern action 7x57 Mauser with a Barnes 120-grain TTSX bullet (or a Nosler 120-grain Ballistic Tip, or a Sierra 120-grain ProHunter) and 51-52 grains of H414 is a thing of beauty -- minimal recoil, muzzle velocity from a 22 barrel of around 3100 fps or a little better (at safe pressures), good ballistic coefficiency and sectional density (so the bullet loses velocity slowly and penetrates very deeply), and outstanding lethality (with a well-placed heart/lung shot) out to 300+ yards.
