I'm not sure about those particular air rifles, but there are .177 and .22 caliber air rifles capable of 50J or more. A half gram .117 pellet at 1600fps is 60J

I'm not sure about those particular air rifles, but there are .177 and .22 caliber air rifles capable of 50J or more. A half gram .117 pellet at 1600fps is 60J. They should definitely be treated as weapons.
