B_b,
Here in WA you are able to use fiber optic sights on your muzzle loader. If you have the newer edition of Bass Pro (has a huge-racked whitetail running on cover) you can go to page 331 and see some of what they have for fiber optics for muzzleloaders. You could also check out their website and Cabelas and probably see more products. I have fiber optics that I put on my shotgun and a I bought a T/C .22 Classic last year with them on and they make a big difference. I can still do a good impression of not being able to hit the side of barn when shooting at birds, but I just think it has to do with the operation of the gun. After shooting the .22 and being able to kick a cans a$$ at 30 yards I was quite impressed with the sights and have been thinking of putting them on my muzz, too. I think I have heard Williams sights has fiber optics also and you may want to check them out. Hope this helps.
