After reading DaveGs post I thought I'd post this slow motion video of a Gray shot with my FX Verminator. Shot was made from approximately 35 yds or so. Pellet did not exit and was lodged in the mid section of the body cavity (Regretfully, no autopsy pics this time). The squirrel was down for the count. Complete energy dump into the animal. Having been using the .25 more and more I find it superior to the .22 for solid one shot kills. The .30 must even be better!
