sticking gball

Unread postAuthor: jr » Mon Jul 07, 2008 12:00 am

I just finished a barrel for my extinguisher cannon and the balls stick in the barrel!!! WTC I used SDR26 just like all the other(2) barrels I built and they don't bind? Its not a hard bind just enough to have to ram rod the ball down the barrel. I know that this is a better seal so I have less blow-by but it is annoying...

Has anyone else had this problem?
