Step one: Run 100 yards to where your rifle is stowed, magazine loaded but chamber empty, yank it out, then run 100 yards with the rifle, chamber still empty, to your firing point.
Step two:**_ You have 15 seconds to get into position, crank a round into the chamber, and get off your first shot. Then you have to take two more shots, for which you have an additional 10 seconds each. All three must be in a vital zone for any of them to count. It's an all-or-nothing proposition, based on the fact that it's smart to shoot elk repeatedly as long as they're standing. I've seen too many of them take a hit, decide that it's not fatal, and run a couple of miles. You need to make all three shots within the time limits.
