RE: some questions....
Just about any of the name brand companies like CVA, Traditions, etc offer guns good enough to get the job done. The Cabelas gun are the same guns (most of theirs are Traditions I believe) as the Namebrand guy' s pieces. Actually most all of these " antique" guns are made in Italy and just imported by these companies anyway.
To be honest, if you' re really looking for a quality flinter, the Lyman Great Plains guns are the way to go. They' ll usually run you around $300 - but they are a big step ahead of the " bargain basement" rifles on the market.
