22's

The Stinger and Velocitor's have longer cases, more powder, and from handgun barrels 6"-9" will penetrate about 3"- 4" into a solid beef brisket (other tests have shown 12" in ballistic gelatin). Then again, all of the ammo in the pic penetrated about the same, so if you're up against an enraged and therefore dangerous brisket, the choice boils down to what feeds fires and flings best in your weapon. Not pictured is the Remington Viper that'll do something along the lines of 1500 fps in a 20" barrel, and since it features a solid bullet will give decent penetration in small game but won't expand to .34" to .38" as most of the other .22 hollowpoints do.
