I think all makers of firearms, and to a larger extent, industry as a whole, are guilty of copycat tactics. One company comes out with a big seller, and all the rest rush to get their version of the same thing out. The type of action on a muzzleloader is a good case in point. The only real advantages afforded by one inline action over the other are a matter of conveniece, be it cleaning or loading and priming. In a smokeless firearm the advantage of the bolt style action over the falling block type is easy to see, it allows a repeater style rifle. A muzzleloader is a one shot deal, the only thing a bolt will get you on a blackpowder gun is a familiarity if your regular deer gun is a bolt. There is an advantage in reliability in wet conditions with some types over others, but I think really you are just as well off with an old style knight as you are with any other type of action. I do really like knight rifles though
