Reflecting my own uses against that department list, I find one big glaring hole. It's covered here and there on individual topics within some of the departments, but what about a department devoted to HUNTING WITH TRADITIONAL MUZZLELOADERS? I'd subdivide it into big game, small game, shotgunning/birds if you thought it would help. Truth be told I fire about 300 shots at small game or birds for every round fired at big game, though I suspect most of the yack is going to be about big game.
Another good department would be PLINKING OR FIELD SHOOTING WITH TRADITIONAL MUZZLELOADERS. Most yack is about shooting on the range, but what about getting out in the hills away from the range for some serious fun. In my old archery days we called it "roving," just wandering around picking targets of opportunity. Best shooting practice ever for hunting with a bow, and the same is true with a muzzleloader. Can't tell you how many rocks and pebbles I've blown up in creek beds, ice chunks and snowballs in winter, or clam shells on our deserted beaches. Sure is fun, and fun enough to chase me off any formal range. I'm real curious what others are doing for fun, and I'm always looking for new ideas. Anyone ever launch boats (sticks) in a river and shoot at them with your shore battery (rifles)? Buds and I do it all the time, with "hits" being shots that launch the sticks into the air, but extra bragging rights when two pieces of stick go up on top of a cloud of spray. Dat kinda stuff.
