I was fortunate to draw unit #15 in NM and immediately began research on a muzzleloader. I've never owned an ML before so everything was new. I finally got all the pieces together I needed and went to the range to find out I'm not able to fire the primer. I was going to run a couple of primers through w/o a load as directed by Knight but I couldn't even get the primers to go off? I tried Remington Kleanbore 209 size and Winchester triple seven 209 primer and used Knight's Full Plastic Jacket with both types of primers. I have the breech that came with the Disc and I believe it is the correct breech for FPJ. It's like the firing pin isn't reaching far enough to even hit the primer. I'm glad I have four months before season because based on my start I'm going to need all of it.
