Question for the learned anons ITT.
Picrel are external ballistics charts for 2 hypothetical bullets.
On the left:
50gr@3000fps=1000ft*lbs
G7BC=0.3
On the right:
100gr@2121fps=1000ft*lbs
G7BC=0.3
So the bullets have the same BC, but different bullet weights. Let’s say they’re the same caliber and the difference in SD is compensated for/balanced exactly with form factor. Whatever. I adjusted the velocities to produce the same muzzle energy.
My question is, how come they do not lose the same amount of energy per unit distance? Or the same percentage of their velocity per unit distance? I would’ve thought perhaps the light and fast bullet would bleed energy more quickly since it’s going so much faster, and so there’s more drag on the bullet. But it’s the other way around. The light/fast one loses 2.6% of its velocity and 5.2% of its energy in the first 50 yards, while the heavy/slow bullet loses 3.1% and 6.1% respectively. What gives?
