Air rifle pellets ballistics in air is way different then normal bullets. Normal Bullets are stabilized in air by rifling. Normal bullets weight sits in rear and need this stabilization. Air rifle pellets the weight sits in front of nose. The skirt merely helps it follow trajectory. If you throw a pellet it will on own turn it self facing forward. A bullet will turn around.

This is reason FX went into smooth bore. As you dont need to spin a pellet at all. This can be seen on Airarmshunting channel where a video is posted about it.

A pointed pellet is less accurate as the point pushes and cuts through air and if spinned can go little off trajectory loosing accuracy. Hence the reason all match Pellets are either flat point on Dome/Diabolo design.

Flat point will also casue more damage to target due to flat larger surface hitting target. Where Sharp point smaller point.

Ive used some Hades J&B while back. They are devastating on targets.

But Avoid sharp point for accuracy and hunting. They offer zero advantage over dome.
