AM comes in several sizes. GFC has all sizes in one bag. I have broken up AMLM for our small HSB. For small BG GFC is good enough. You don't have to grind up AM. You can put some (several lbs.) in a couple plastic bags and roll the car over it a couple times and be good enough. A cinder block as a crusher also works. You can grind by hand and that will work. BG will eat ground up pellets just fine.
