don't be too eager to dismiss what may seem like nonsense. in reality it (the bouncing) works quite well, has no negative effect on accuracy, insures no air spaces in the tube, the ball is not "deformed" via the rod, compacts (not compresses) the main charge, and it's done me well in woods walks and stake cutting matches. hammered or smacked hard short starter tight target loads have a far greater chance of ball deforming and yet accuracy is far from compromised.
