I'm packing in around 2-3 miles on average and hunting some steep country but the weight of the gun at present doesn't bother me. I believe a #5 contour would add about 1/2 lb.
Ask if your barrel maker of choice if they will do a custom contour. If yes: Straight taper the barrel 4-5 inches at 1.25, begin taper where 1-2" after straight shank ends, reduce to .800" then straight taper to muzzle ending at .650-.675" and flute it. barrel length 26".
If no custom contour, then do a #4.5 contour, just slightly larger than your factory barrel, and flute it.
