I have a crossman 1000x which will kill them. Latley I have been using .22 shorts to shoot squrreils. They are very quiet. Some of theose pellet guns are just as bad as .22's.

I have a benjamin sheridan 392 .22 cal pellet rifle and Ill tell you what, I love it. I just bought a bushnell 3-9x40 scope for it and a b-square rail for pretty cheap, the rail was 31 bucks shipped from midsouth shooter supply and I shoot 14.3gr pellets out of it, great gun and a good amount of power, dont be discouraged by the 685fps it pumps out, its plenty, and Ive had this gun for a month and dropped quite a few squirrels no problem, they fell down dead. The only problem I have with it is the iron sights, they arent very good and the elevation screw on it fell off and I couldnt find it. These definitely need a scope, but for the money their great guns. I paid $110 for the gun, and bought a nice scope for about40 bucks. Overall, If you have a choice, buy a benjamin sheridan 392 .22cal, .22cals are better IMO, Ive had both. And am going to buy a gamo maxima with a scope soon in .177 cal.

i use a air arms s410 xtra .22 pcpair rifle , it's a very nice gun ! look's and feels great and load's of power at 36 ft/lbs as standard.

wow, that is a nice gun. Im going to buy a GAMO Hunter Maxima with a BSA 3-9x40 scope.

ive got a powerline 880s. it really sweet. ive never shot anything with it yet but i know i can kill rabbits with it because my friend does and this gun only has about 625fps, but im thinking about getting some pba raptor ammo it supposed to increase your guns velocity by 25%. pretty cool.
