Brux 45 Caliber #6 Barrel Blank
This is a very popular contour used in the making of long range, super powerful smokeless muzzle loaders. The #6 contour will save you a pound or so in the overall weight when the rifle is finished and it will shoot just as good as the #17 contour. By using the #6 contour, you will loose a little weight in the overall build but gain a little more recoil. This barrel blank is 31 inches and can be finished up to 30 inch. I prefer to cut off at least one inch from the muzzle end to get to good clean, sharp lands and grooves.
90% of my builds are finished at 26 inches as this is all that is needed when shooting smokeless powders. If you are going to shoot blackhorn 209 or black powder substitutes, you might want to finish your barrel at 28 inches.
