I have a Remington BDL 700 in 300RUM. I have tryed factory and handloaded ammo and some results were better than others. What kind of accuracy should I expect out of this big gun? Everything is factory except the leupold on top and the limbsaver pad. (I haven't gotten a chance to try it out with the new pad on it yet). I'm guessing sub MOA is out of the question, but what sounds like reasonable accuracy out of this rifle?
