Dont be diss heartened if you are shooting all over the place to start with. Most of us missed the target compleatly when first starting out. Try using both hands to grip the pistol untill you gain confidence. 15 grns is an acceptable starting point so try bigger balls and see how it goes two handed. If you shoot well two handed but badly with one its you, if you shoot badly using two hands its probably your load. Half the fun is trying different loads etc. Iv been using my rogers nearly 10 years and i still miss the black sometimes, with my short barreled ruger im all over the place. Keep practising, it does get better.
