dunno if this is rite but this is how we do em. get ur shottie packed with just enuff baccy to hold the weed, then ya weed, then cover the rush hole and slowly start to suck the smoke into the chamber untill its filled, then once a couple off hotrocks av fell through or untill u can tell or whatever, uncover the rush hole n then just inhale the contents of the chamber in one fell swoop
