How deep Can a 22 LR caliber bullet penetrate ballistics geletin?

There are many different variations of .22LR rounds. Some have higher or lower grain bullets, some even have different shapes, and different brands could be higher or lower quality. These factors, along with the distance from the geletin, affect the bullets penetration ability. The length of the barrel of the firearm can also have an affect because shorter barrels don't allow for as high an exit velocity for the projectile.
