i tried it with conical like in the vid, i also had a go with ball, put the ball on the end of the paper tube and add a drop of super glue (it will spread around the ball paper joint) the thing is that some one made the conical's and the balls for me and lubed then with lee alox (lee had an advert of a bullet coated with alox the other side of the bullet was been melted with a blow torch) super glue will stick to alox and the alox really does hang on to the bullet as well as lee says!!
