Paintball Breakage causes

So I just got myself a new Big Shot 14" and I am very reluctant to think that it is really this inaccurate (worse than stock barrel) and breaks these many balls (1 in 20) So I am wondering why I am breaking soo many balls. What are reasons for ball breakeage either than low quality paint, because I have used both with only slightly better effect with the better paint. My gun is a new Custom Pro. There are no chips in my sear, and I shoot only about 1-2 bps (I play woodsball)

Well I have played at two places this past weekend after getting my new barrel and I havent yet tried the stock barrel again, both of these places are strictly against outside paint and so I have never really had a reason to buy my own paint since they are the only places I play. One used quite good quality paint and the other place I go much more often (today), seems to use a varitey of paint and I don't know what brands they use, but today I was absolutley disgusted when they handed me my bag of paint, the balls had a transparent shell and you could clearly see how the paint had solidly settled(and they wont let you use your own paint ). So I am pretty sure that, that would be a major cause, the only reason I wonder if that is the only reason for this is beacuse I experienced alot of breakage with the good quality balls at the other place. I am going to buy some very high end paint and try interchaning barrels(I use HPA). Is there anything that could be neither barrel nor paint?
