Strangely enough, when I take my time I often make an arse of it. Do it without thinking and rarely have a problem.This is what I do and have always done. I just kinda stuff tobacco in there a bit at a time till is seems right, tamp a bit with a finger and light it. If it’s not perfectly filled, who cares? Sometimes I do take my time with it, though, and try to get it as perfect as possible.
