Geeze I've killed a truckload of squirrels around the yard here with a bunch of different pellet guns over the years. My 40 year old Daisy 881 has probably done in the most. It throws a crosman round or flat nosed .177 lead pellet at about 630 fps with 10 pumps and usually kills them instantly with head shots. Broadside double lung shots kill them too but not instantly and they'll usually run aways or hang on up in the tree for 30 seconds or so before they fall.
