Pellet Design Obsessions

Here's an interesting little study I did on the air gun page I'm administrator of on Facebook. I lined up the commonly used .22 pellets I have to see how they differed in length. Left to right; Crosman Premier Hollow Point 14.3gr, H&N Field Target Trophy 14.66gr, H&N Sniper Light 14gr, H&N Baracuda Green 12.65gr, Gamo Platinum PBA 9.7gr, Gamo Rocket 14.39gr, Beeman Silver Bear high shock hollow point 12.65gr.

​This time, same pellets in the same order, but with one showing inside skirt area. Note how each one is different? Also notice how the H&N Sniper Light's skirt looks like the nozzle on a rocket booster?
