Query: PMI RPS Premium Paintball (Yellow/Blue): Expensive yet popped almost every other ball

after reading other reviews, I used .690 flasc barrel on my phenom which had a Tech T bad karma bolt(soft tip). Almost every other ball popped inside the barrel. Even after cleaning it, then had to switch to a different barrel, they still popped like popcorn. I thought it was my gun so i used the paint sold there, not a single problem. Maybe it was my gun but I doubt that.
