OK here goes... I bought a Traditions Pursuit and I took it out to shoot it yesterday and again today. I started off using Pyrodex pellets (100 gr) with powerbelt .50 cal aero lite bullets (250 gr) and triple 7 209 primers. I noticed after the third shot that the breach plug was pitch black on the side where you put the primer. After a few more shots I could barely open the breach and when I did the gun would not close back. (on a side note I could not get it to hit a thing!!) So I took it home and cleaned it. Took it back out today and changed powder and bullets. I use Triple 7 powder (100 gr) and Thompson Center Sabot .50 cal (including the sabot) (250 gr) and had the same thing happen with the plug.. they shot a little better groups. Also while I was there both days I had two different guys come up to me and see what kind of bullets I was using b/c it was so hard to get them packed down completely. Today I also took my dads muzzleloader with me in case I could not get mine sighted in due to these issues. When i loaded his it was way smoother loading. So I was wondering if maybe there is something wrong with my barrel that is causing the bullet to be to tight which might be causing the blow back on the primer side of the breach plug... here is a pic of the plug and you tell me if your muzzle loader plug looks like this when you shoot 3 times.
