I have killed a bunch of deer with a .22lr subsonic shell, never lost one and all killed almost immediately. Under special circumstances it will kill the snot out of them.
Not that I plan to replicate it Troy, but I'm curious....where did you shoot them to make them die so quick with subsonic 22? In the ear?
ear hole usually. I shot Rem lead HP subsonics, little noise and accurate. I killed one deep inside the Wilsonville Steam plant hiding behind some boilers. Don't know how it got in there but I know how it got out.
there used to be an old poacher in Tuscaloosa Co that used a .22 rimfire with shot HPs, he killed a lot of deer. They were close and he could shoot pretty damn good with a light on em

Gil Green finally caught him one rainy night.
