I tested several pellet guns in ballistics gelatine today. A daisy 1000x (Rifle), a Browning 800 mag (Pistol), a 22/40 (Pistol), a Crosman 1800 (Pistol), and a Crosman 357 (Pistol). All are .177 cal except for the 2240. The 1000x rifle, and the 800 mag penetrated over one foot of ballistics gelatine at 5 foot distance. This meets FBI Protocol. The 357 and the 2240 both averaged out near 4 inches of penetration. The 1800 would just bounce off of the gelatine, unless the gun was fired from point blank barrel contact on the gel. This causes me to question how reliable ballistics gel is as an indicator for bullet incapacitation. Two of these guns met the FBI protocol for stopping power, yet they are close range squirrel guns at best, and the 1000x rifle can take something the size of a woodchuck or a coon inside 30 yards. I highly doubt any of these pellet guns can penetrate a rib cage and still stay on track, to severely damage a vital organ. They still meet FBI Standards.
