"Smaug"Welcome!
I watched Ted's review, about the copper-plated pellets being preferred. Mine, a late model one, didn't really like them. They were a VERY tight fit in the breech.
I replaced the stock barrel (a bad one) with an older (good) stock barrel.
In each case, it likes H&N FTT and H&N Baracuda Match pellets the best. Baracudas are pretty heavy for it, and are shooting down in the 500s, which I don't like. It also does well at shorter range with PolyMag Shorts. Crosman Premier Domed and Hollow Point also work well, but are not as consistently good as the H&Ns. They CAN shoot tighter, but you get the odd flyer here and there, which is REALLY frustrating. Save that as plinking ammo.
I have a moderator on mine, and adjusted the trigger tension screw out, and it is a sweet shooter. It has grounded quite a lot of pest birds and squirrels with just the right amount of power for short-to-medium range backyard use.
It turned the lights out on this stinker, early this spring:
