Hi , im thinking of getting a Daystate Air Ranger 177 tactical , but im torn between the sub 12 ft lbs or the 177 18 ft lbs version , i dont want to lose accuracy by going for the fac model , i have read the 18 ft lb is good with 10 grain pellets , does anyone here have the fac Air Ranger in 177 that can reassure me i like the high power for 70 yard shots , i know its all about accuracy and i do use chairgun , i have an Air Arms TX 200 177 sub 12 and could not be happier with its performance , can any body give me advice Please , Thanks Fernando
