You can pick your friends, and you can pick your nose, but how deep do you pick your vent? Is it enough to just push any errant grains of powder out of the way, or should you push the pick all the way to the far side of the breech? Peter Alexander says to make sure your pick reaches all the way to the far side, so I assume that he's hinting that the latter is preferable, opening a channel all the way across the back of the powder charge. I get the occasional FITP, and I'm experimenting with all the variables--how much priming powder to use, banking it away from or up near the vent, etc etc. Also, the vent in my rifle is slightly back of center of the pan, and does that create mis-fires or help ignition? In this day and age, there's so much to learn!
