Hi Ricky,
First thing I would do is test different pellets out. Try experimenting with some different ways of holding the gun see what happens. even try another scope if you have one as a double check if not getting like you want..
There is no need for powderburner cleaners on an air rifle as no heat or copper, in fact it can do more damage than good, it will disolve seals etc.. I only use goo gone a weed whacker line with melted end and a patch pull through or a wool pull through untill clean. Any brass or metal pull through can damage the rifling on an AG and ruin a good barrel. Then after goo gone you will have to fire 100 +/- shots to re-season the barrel it will need some lead to work well .
I only clean the barrel of airgun if accuracy changes usually more than 3000 shots. I wish I could find a link with better info on this subject ..hopefully others will add to all this and help you out. Tony
One other thing I have noticed is that most accurate AG barrels have some degree of choke (not all), I use a 1/8" wood dowel and push pellets through from the breach to feel the tight and loose areas of the barrel only the last few inches seem to matter.
