It's as much about weight, distribution ,volume, and material, as it is aerodynamics. At the velocities we're shooting at, most flat nose darts are going to perform equally well aerodynamically.

The genuine Nerf Accustrike darts I weighed were about 1.081 grams. The Precise Pro darts weighed about 1.054 grams, and are 2mm shorter. Using a stock FireStrike I measured the velocity of Accustrikes at about 60 FPS. The Precise Pro darts average 80 FPS. So even though there's a 2.5% difference in weight, there's a 30% increase in speed.

I believe the main difference is that Precise Pros are .5 to 1 mm wider, and the shaft of the dart is much smoother than Accustrikes. They fit into the barrel tighter, which means they trap more air behind them, and maintain a better seal all the way to the end of the barrel.

The other main characteristic of the Precise Pros is they rarely fishtail, if ever. So they tend to be more consistent. I attrubute that to aerodynamics.

So maybe it's not exactly proof, but there's some decent data for ya.
