Amen to what HBP said. Round balls are STRICTLY for close range shots. They simply don't pack enough energy down range (that comment ought to get some remarks, but I'll stick with it).

I personally like the T/C Black Diamond ER. It will shoot 200 yards - although I can't say that from personal experience. I'm just not good enough with iron sights at 200 yards to take a shot no metter what. But my T/C has done very well for me. I've also heard good things about Knights. Just make sure that what ever you get uses original stye percussion caps and that they are exposed to the elements. Then don't put a scope on (but fiber optics are legal). (HINT: I love musket caps. They burn wayyyyyyy hotter than standard percussion caps.

Then, most important of all, PRACTICE. I hate to lecture, but I've done a lot of muzzleloading, and I don't know but one or two guys who should consider a 200 yard shot with an open sighted muzzleloader.

BTW, I also like this bullet: It's called a Harvester, and I've whacked lots of elk with it. Never had a problem with them. You can order at : WWW.claybusterwads.com

Good luck!!!
