Sassy,
I own a White Mountain Carbine and have shot the Scout, both have barrel twist rates that are generally considered too fast for roundballs, unless they are shot with reduced-(non hunting)-loads.
My WMC is about 14 years old and has been shot alot, with zero trouble, and it shoots conicals and some sabots really well. It's my main deer gun. The Scout, I didn't like it, the nipple is part of the breach plug, it just seemed a little odd to me. I would contact T/C to see if they still have parts for it.
