Turtle,
I recently finished a rifle in the Bucks County style with a B weight, 38 inch, .50 caliber Green Mountain barrel. It is a nice handling rifle and a pleasure to carry in the woods for hunting, which is why I wanted it. However, it could use a little more weight in the barrel to hold better for target shooting. IMHO a 38 inch barrel in C weight or a 44 inch barrel in B weight would hold better for target shooting. It's hard to find a combination that is ideal for both hunting and target use. I guess you just have to decide how you'll mainly use a rifle and build it to support that concept. Just my tuppence.
