I use Lyman #55s exclusively for all of my reloading, which includes extruded powders. The key to throwing consistent loads with the #55 is to throw it with authority, not matter whether flake, ball, or extruded. The tapper helps immensely to consistently fill the cylinder, but throw it quickly and it will shear the "logs" and allow it to drop the load. Don't give up on it, just learn how to use it properly. The more consistent you are with your throwing technique, the more consistent your thrown charge weights will be.
