Many years ago I bought a forty caliber TufRam from Target Zone Sports. The barrel arrived with a slight curvature. I used this in competitions for several years and achieved my highest scores with it. I believe that the darts tendency to continue in it's initial direction caused it to battle the tubes insistence that it change course resulting in a dart tip that is held near the bottom of the tube rather rather flailing about randomly. It is mere speculation but I believe it deserves some consideration.
