I am happy to report that I had a very successful Muzzle Loader hunt. This buck was feeding slowly as he headed to his bedding area, but he didn't want to stop in any one place for very long before moving on to the next edible morsel.  I ranged him at 310 meters and simultaneously got the 10 degree downhill angle from my Slope-Shot stuck to the side of my rangefinder.  It didn't appear that he would get any closer so I dialed in the distance, checked my cut chart, and then knocked off one minute for the slope.  There was no wind and I had my muzzle loader positioned solidly on my tripod rest, so I pulled back the hammer, steadied up, and squeezed off the shot.  Larry Bundy, a good friend and hunting buddy, was sitting next to me and watching through his binoculars at the shot.  He told me that I had hit the buck low in the shoulder.  He ran a total of 20 yards, stopped, flipped over backwards and died before I could get my ramrod out for a reload.  After examining the buck, I found that the bullet had entered the bucks' chest a couple inches above the point of the elbow, cutting the heart in half, and exited the other side with plenty of remaining energy.  Larry told me that he had heard of people accidentally killing bucks at long distances with muzzle loaders before, but I was the first he knew of that did it on purpose.  All the gizmos in the world won't help if your gun shoots 12" groups, but I have been blessed with a very accurate gun.  I also have a great ballistics program to tell me what my bullet will do downrange, and gizmos like my Slope-Shot and rangefinder to help me dial in the exact point of impact needed for a clean kill.  Thanks for a very usable product.  I would love to hear about any updates to this design you might implement in the future. - Don Leonard (UTAH)
