My BIL got a new Barrett M99 in .416 and at the first range outing it sent a round over the berm when he closed the bolt. Finger nowhere near trigger. He was able to duplicate it without a round in the chamber. Close bolt, click. He was also able to drop the hammer, closed bolt and finger off trigger, just by taking firm hold of the grip and putting tension on it.

Anyone heard of this before? Rifle is on its way back to factory, but I thought I'd ask to see if this was a common thing, or not.
