I bought a Lyman Great Plains Rifle!

I shot it again Saturday. I'm out to 100 yds now and getting them at least in the black. It would be better but I get flyers that open up the group. I'm swabbing the bore once after every shot with straight Windex on a patch over my jag but even after less than 10 shots it still gets grimy enough to where I have to pound on the ram rod sometimes when it goes through a sticky spot. It could be the Goex powder and I might get some Swiss if they have any at the black powder shop. Maybe it's cleaner.
Thanks.

Mine is a .54,   just a bigger hole.  Sounds like you got the ignition stuff figured out.  Ive shot both 50 & 54, and both seemed to like a thicker patch (.490 & .530 balls with .018-.020).  I use P-dex P, with prelubed wads.  Barrel stays loadable all day  I use the fixed rear sight,,Still working on the front blade.  They usually require filing down.  Depends upon what your sight picture is.

Madmedic are those wads you use commercial or home made? That sounds like it's worth a try. I had to file A LOT off of my front sight and now that I'm out to 100 yards it's even going to need a little more. The ignition problem is gone. It did happen once this past Saturday though. What I do now is wipe off the nipple every few shots and make sure the cap is pressed down hard when I put them on.
