I have a somewhat new pipe (i've smoked maybe six bowls on it) it's a Savinelli 316 KS. The problem is that the very bottom of the bowl is a little lower than where the hole is. So when i get to the very bottom of the bowl there is a bit of tobacco left over. There is no way i can't smoke it all they way down. Is this normal, or will that little space on the bottom of the bowl fill in with cake eventually?
