No matter what rifle you purchase, someone is not going to like it for one reason or another. If you are happy with the rifle, that is all that is necessary.

Powders - Blackhorn 209 is a good powder but if you can not find it in your area, then go to Pyrodex RS or Triple Seven 2f. Actually I would shoot the Pyrodex RS. It is a good consistent powder. Granted it is dirty, and you have to clean the rifle after a day of shooting, but then I clean all my rifles after a day of shooting. No matter what kind of powder I get.

Projectiles.. Get some 250 grain Shockwaves for now. Then if you can find them on line order some 250 or 300 grain XTPs or Speer Deep Curl. Both of them are .452 diameter and usually shoot well from all inlines.

Tools you might need.. powder measure, lid for the powder jug, primer extractor tool, anti seize, loading jags, cleaning jags, a range rod if you want to spring for it, and a dog bone capper. You might also want to pick up some gun oil, cleaning patches and black powder solvent, and a bore brush would not hurt either.
