Hi Bob,
Lovely new toy!!
Give it time. Concentrate on technique - all aspects - stability, breathing, trigger control, follow through, consistency and repeatability of technique, especially.
The gun will also require a little bedding in time.
Just relax, let it do its thing.
Gun wise, just check all the basics - any loose fasteners etc. Parallax error?
Give it plenty of time. It may be that the pellets you're using are not the best for your rifle / barrel, but maybe explore that more once you've got to know your new baby more intimately.
Oh, and don't overdo it! Your shooting will go downhill if shooting too much / trying too hard. Take breaks and RELAX.
