I live in a rural neighborhood with about an acre between houses. Up till now I have been using .22 sub sonic shorts to deal with
garden raiders but lately have not been able to find them anywhere.
Stopped by the local GS and the guy says try these. .22lr with a 20 grain bullet and NO POWDER.
Just the primer and thats it. He said you get about 560 fps with a rifle.
Took some home and tried it out on a beer can full of water at 50'. Punched a hole clean through and was supper quiet.
Made about as much noise as dropping a quarter on a concrete floor, and was quieter than the .22 short
