I have an RWS Model 48 in .177 and just love it. I was shooting at a target in my back yard at about 30 feet distance. Behind the target I have a small wooden wall with a 2x4 Redwood cap on it so I can walk on the wall and cut back Ivy growing behind the fence. I missed my target shooting RWS Wadcutter pellets and hit that cap which is oriented with the smaller 2" edge facing forward. Redwood isn't the hardest wood I will grant you that but that pellet entered the wood to a depth of over 1.75". I think the RWS Model 48 in .177 is more than sufficient for your pest problems. Recently on "American Airgunner" (a show I get on Directv satellite service) the host said that the this .177 RWS was powerful enough to take squirrels, rabbits, birds, and yes even raccoons. Raccoons surprised me but a well placed shot will do the job everytime. If I had it all to do over again, I may have purchased the Model 48 in .22. I am however not disappointed in my .177 in any way. What ever you decide to buy in RWS you won't be disappointed. This gun never fails to amaze me. I like it better than some of my gunpowder guns. It weighs a fair amount sure but so do my gun powder rifles. I don't get this...it's too heavy to carry around stuff at all. Enjoy your RWS. I know you will.
