Reply to comment by pptengineer in Does the spinning of a bullet have any effect on its drag? by Eastern-Ability8411

Apologies if already addressed, but does the weight of the projectile matter? Or does speed negate it?

Weight does not affect drag force, but it does have effects on the bullet’s flight path. Only the bullet geometry and the medium it flies through should affect the drag I believe.

No though you will have the same force acting on a heavier bullet, so the drag will affect the bullet less. That is why heavier bullets have higher ballistic coefficients.

Sounds counterintuitive but makes perfect sense, thank you. It's why downhill skiers are faster when they weigh more.

Ya or why a balloon falls slower than a bowling ball in atmosphere when both are smooth and round.
