Hi and welcome back to the hobby. Are you trying different pellets? Your rifles,like most,will shoot a particular brand,weight,and style of pellet or pellets better than any other.Every rifle is different, even within the same model, and made inline beside each other. With some that can be alittle picky to the very next one that is partial to a brand ,weight,and style of pellet. You may have a very accurate rifle in your hands and not even know it. So get yourself a good selection of pellets to have on hand to try out. And when you upgrade you will have a good assortment of pellets to try. Finding the rifles favorite pellet is one of things I enjoy in this hobby. good luck
