We've gotten so far away from primitive that we're driving automobiles to the deer woods and wearing Goretex, too. We're cherry-picking the whole "primitive" thing, IMHO.
If it loads from the muzzle, it's a muzzleloader. You get one shot at Bambi, then the ramrod comes out. Truthfully, inline-ignition and scoped muzzleloaders have been around since the Civil War and before. It's much grumbling and to-do over nothing, really. Sadly, in the big picture, such pissing and moaning doesn't foster much in the way of welcoming new shooters to the sport.
