I have both a .177 and a .22. I have used both guns to whack Rock Chucks and a varity of birds and other critters. It has been my experience that a head or heart/lung shot with either is fatal. The .22 seem to kill on the spot a bit better and it does seem to produce a bigger pop when the pellet hits. A .22 gun sighted in at 20 yards shooting ~600fps will drop about 3/4" at 30 yards, still minute of squirrel. BTW my .22 is a RWS M-34 Panther with a BSA 4X scope and a C-Mount. The gun is very accurate (1 holer @ 10 yards) and shoots 14.3gr pellets at just under 600 fps (rated 800fps). The .177 is a RWS M-46 and shoots 8.3gr pellets at 750 fps (rated 960fps) and drops about 1/2" at 30 yds. I'm thinking about selling both and getting a slower .177 Beeman R-7. Anyone need a pellet gun?
