+1 I have a decent selection of spring and PCP powered airguns, but for a grab and go garden gun the old Sheridan Streaks are hard to top.
In my youth I patrolled the woodlots with a Silver Steak and it accounted for untold numbers of starlings, squirrels, rabbits and an unlucky 'coon. FWIW, my buddy's .22 cal Crossman pump action CO2 would barely penetrate a fox squirrels skin (granted the pellets were of the flat nose style) while the old .20 cal Sheridan Cylindrical pellets would completely penetrate said squirrel. I still have my old SS and it still works just as well 50-some years latter and I keep a peep sighted Blue Streak at the cabin to keep the pine squirrels in check.
