I'm using the no excuses 460gr bullet, 85 gr 777 ffg (I would like to use more but my groups open up), and musket cap. You need to use something between the bullet and powder or it won't group at all. I had good luck with a traditions "wonder wad" but ran out and don't have a local source so I've been cutting the petals off of a harvesters crushed rib sabot and using the base between the powder and bullet and that is working just fine. There is quite a bit of drop at 200 but with the Williams sight with target knobs I can adjust for that. Check out the muzzleloader forum here on rokslide there are guys that know a lot more than me, I got my muzzleloader this spring and have learned a ton from them.
