I know this is relative. I have done a lot of research and I keep coming back to the Crosman 2100. I am looking for the best air gun under $100 that kills squirrels easily. I am not sure I want to pump 10 x for one shot so if there is an even better air gun that is not pump or co2. Maybe spring loaded please let me know. Also it has to shoot .177 cal. Let the arguments begin. Lol Thanks. One other thing which do you think is the better gun. The Crosman 2100 vs. the Gamo Varmint?
