For years I shot at the Tall Trees Rendezvous in Crescent City Calif. For about the first dozen years we shot at a location called Wilson Creek. You could hear the Pacific ocean at night, we were that close. Mornings were so foggy, you could eat it for breakfast. I found that 4F turned to mud before it got in the pan. An old trade call Trade Jack told me to prime from my horn, and forget 4F, since the old timers didn't use priming powder anyway. I did, and never looked back. After literally years, of standing, and waiting, for some nimrod to clean the black mud out of his skeeter nosed priming horn, and having experienced the detonation of a couple of priming horns, and/or flasks, at other venues. I think I made the right decision. Besides I'm so old now I can't flinch fast enough to make any difference.
