I was hunting Montana for Mule Deer and had a doe tag left .We saw one up the valley and the guide ranged it at 505 yards.I got down on my bipod. Just as I started to pulled the trigger the leg on the bipod slipped as the gun went off.Knowing I missed I stood up .The guide slapped me on the back and said good shot.I looked up on the hill and there laid my doe.My friend and I walking up to the the doe and my friend said he saw dirt fly when I shot.Sure enough ten feet in front of the deer was a mark on a rock.It had hit the rock and caught the deer in the neck and dropped her.The guide said how was going to explain this one .I said every one can hit one straight on how many can bank one in
