RE: heavy barrel vs. sporter barrel for carry
For me, there is a certain perfect rifle weight that generally involves a #5 (Shilen, Krieger, or Douglas) contour barrel. These are around .710 at the muzzle, and are about 1/2 way between a standard sporter barrel and the varmint profile. Total weight of the gun is about ten pounds with scope, sling, etc. Heavy enough to be very steady at the moment of truth, but light enough to carry a few miles at high altitude.
