Thanks icthruu, but do you have any information on bbl lengths greater than 22"?
Is there any negative effects on the flight of the bullet with a longer bbl or am I just toting around more steel pipe than I need to? This will definitely be a ground hog rig and not meant for stalking around the woods, so the weight is not a real issue, I just want the most accuracy and velocity I can wring out of the bbl and know that length and twist rate need to be optimal.
