I have a gen 2 FX Impact in .25, 1 shot stops on squirrels with power level turned down. I'm always concerned with shooting through squirrels and doves. Quiet in the yard. Great shot count when pesting in yard and good count with full power hunting. Have not had any problems yet. Good on raccoons. .25 JSBs are economical, accurate, small and light enough to carry a lot and not be a "drag". I recently added the 700mm smooth twist X barrel with shroud and the 26 count extended magazine purchased through Utah air guns. Impact seems a little quieter cause, with the longer barrel I turn the power level down even more. The Impact was accurate with the 600mm barrel and is still accurate with the 700mm barrel. I seldom have need of long distance shooting, I have to travel back to the farm for that and haven't since installing the 700mm brl. I wish the makers of the pellet pen would make a .25 pellpen. I use them to load all my .22 guns especially the FX magazines. No fumbling or dropping pellets in the field. I use a mounted light and a fixed 4X bug buster for night racoons and switch to a 3-9X for day time. Don't seem to have the raccoon problem since federal wildlife convinced a neighbor lady it was illegal to feed wildlife in her yard with a large tub of moist dog food and allow them to nest in her basement so the 4X is on the shelf for now. I like the gun. I keep it next to the door when I'm home and hide it when I'm not. Also I've had good luck with all the major dealers for sales and service, AoA, Utah, Airgun depot, Pyramyd,Randy in Colorado springs, co. Shoe box compressor, and Joe B( never remember his last name) who sells the best and safest bottles, tanks, gauges, hoses and valves. I have personally seen what 200 psi steam will do to a straw broom or stick let alone 3000psi air ( shoot a little air into your flesh then stop the bleeding and look for blood clots). I willingly spend a little more money for my safety. Well that's enough out of me. Good Shooting!
