I'm sure that for many, it depends on the tobacco, the pipe, the puffer, etc., but for me the packing is all prety much the same. Like the others who posted in your thread here, I simply put pinches in the bowl, tampering lightly after each pinch, until the pipe is full and the tobacco is a bit "springy" at the top. The draw should feel like sipping soda through a straw; if the draw feels like you're sipping a milkshake, the pipe is packed too tightly, so it's best to start over.
Oh, and many tobacco blends are too "wet" to smoke right away and these need to be dried and depending on the blend, this drying time can take from 10-15 minutes to as long as several hours. The "pinch test" determines if and when the tobacco is ready -- just take out a bowlful on a plate or sheet of paper, take a pinch between thumb and forefinger, lift it a few inches and drop it back on the plate/paper -- if it clumps together, it's too wet -- if it falls in pieces/ribbons, it's ready to pack.
