There is a lot going on in a chamber in the tiny window when a round goes off. "That is my understanding also, & why I 'try' to explain to people why not using a filler (with service level loads of +/-85gns of BP) in a .577/.450 isn't going to cause any issues, as the powder 'slumps' forward creating a solid wall of powder between primer & bullet.".
