I think what Reb was referring to is Chore Boy. I use it myself. Poor Boy to me is the muzzle loading, iron mounted, Southern rifle that is devoid of any fancy features found on the longrifle. The fancier ones do have a buttplate and even a metal patchbox.
Aye, Chore Boy. Don't use off-brands. Most (if not all) are copper-washed steel. The only pure copper version I have found is the actual Chore Boy brand.
Works great. I don't even bother with other methods, any more.
