thru a rifle barrel, and still had "match" accuracy. Teuf says McMillan would like to know, too. While you're at it, ask him how he starts a 308 bullet at 2700 fps, has 2200 fps left at 600 yds, and is down to 1100 fps at 1200 yds. See, Hard Rock's got this barrel and physics stuff ALL figured out. Now if he could just learn how to shoot and fight, and grow a pair, he might FINALLY amount to a crap.
