Greets,
Well, I chose percussion, sidelock .50, when I bought. I kinda like the traditional take on it, might eventually get to the "purist" stage and go for a flintlock, but I am a bit scared to try that just yet.
I dont ( anymore ) knock those who want to use an inline or other more modern muzzleloaders, if its legal in your state, go fer it, they do appear to be more powerful and accurate, (inlines). In my homestate, forthe Muzzleloader only hunts its got to be open sight and open ignition.

Just my uneducated opinion!
