I like to dry the tobacco some first,then fill the chamber and compress the tobacco to where it retains a springiness,and the draw is not effected too much.When I light,I ensure the entire surface is ignited,and glowing.I’ll smoke for a few minutes,then tamp the ashes down a little.This is just very general guidance,and my opinion only,
because the issue of how one smokes one’s Pipe is very subjective,to be settled on one’s own terms.
