I recently purchased a new Browning BAR in .308 and I am having a heck of a time getting the rifle to group decently. I have tried several different brands of ammunition but nothing seems to group very well. My Browning Bolt rifles all shoot close to or under 1 MOA including 2 XBolts and an ABolt. I would like the Bar to shoot as well but understand the limits of an autoloader. Truth is I can't get the rifle to shoot inside 10 inches. Any recomendations?
