I dont think the APP sticks are for crushing. Never heard or read that. They are suppose to load like 777 or pyrodex pellets but i dont really care for them. I have tried them and they just need to be more cylyndrical and not the odd shape they are. Break and chip too easy. I read the shape is because of hogdons patent on pellets. Now I have seen some new Goex pellets or pre measure loads in compressed form in an ad that says something about crushing them. If you have to crush them , then why not just measure out regular ol loose charges. How do you know to what degree you would be breaking up those charges each time to get consistancy in your loads.
