A few decades ago I was hunting wild boar in Tennessee in a full on sleet storm. Primed that morning and the first mid day opportunity was a clatch. After that we hunted with tooth picks in the touchhole and a cows knee over the lock. When we finally found some hogs again we primed and stalked the devils. Results were a satisfying boom and pork on the ground. I have either refreshed priming regularly or hunted with the tooth pick since and it has worked well from a stand or still hunting. the center of the touchhole is slightly below the flat of the pan.
