Never did shoot my Backpacker not even sure if I ever sighted it in. So that last few days I been trying different pellets with dismal results. So, back to basics, cleaned the barrel. checked all screws for tightness and grabbed more brands of pellets.JSB and RWS Superdomes were frankly terrible. Then, I remembered I had an old (2002) brown box of Crosman ,22 pellets. Heck why not. Lately nothing I have tried Crosman pellets in were really that great.So, who would have known. 15 shots at 20 yards, just cleaned the barrel and the next group after this one was even better.
