I fill my pans with prime. I don't have any wide shallow pans, all three are a bit narrower and deeper than some.
It may not be necessary, but oft times I almost never get a flash in the pan. I do not wipe the pan out, nor do I wipe
the frizzen off. I just load and shoot. Sometimes there might be a bit of carbon block the vent and it misses fire, so I
prick the vent, otherwise, I load and shoot, load and shoot - no wiping of anything - well, you know what I mean.
