Newgamo,
Yeah, like Progun said, DONT shoot the gold pellets thru it, the PBA's, they are too light of a pellet for the powerplant that you have. I have a CFX and I really like mine, it is perty quite, and I guess the pellet of choice for it is the crosman Premiere Hollow point, very accurate and one heck of a tree rat killer. You might try an assortment of pellets from 7.5 gr to 9gr and see what it likes the best. Not trying to advertise for Bob or anything, but if you havent got the GRT III trigger in er yet, ooooh, you dont know what you are missing. I think you will like your new addition. Good luck and welcome aboard the GTA!!!!!!
