Like Water Monkey said, I haven't needed to bed mine. Mine loves Sierra Game King 55 gr SBT bullets with 24.0 gr of IMR 8208 XBR, TulAmmo SRM primers and Federal cases. This load averages .6" at 100 yards with many groups under a half MOA. Not too bad for an out-of-the-box rifle! I have a DPMS AR15 M4, a Rock River Arms AR15 with a 20" stainless bull barrel and a Savage Model 11 Hog Hunter chambered in .223/5.56mm and none of them shoot as good as the MVP.
