RE: Hawkens Kit from Cabelas...??
In that case,the Cabela's Hawkins is an Investarms rifle. The same maker as Lyman Rifles. They are a good quality rifle. My friend has a .54 caliber Cabela's Hawkins and it is excellent to shoot. If you do get a Hawkins, might I suggest a .54 caliber over the .50 caliber. It would be more period correct, it would have more down range power, and be a great hunting rifle as well. They have a 1-48 twist so they will shoot roundball and conicals well.
Good luck with your selection.
