shooting skill, the gun, the load, the holster, start position, firing position, target size, range to target,,movement(either of target or shottist, or both)light, use of ear protection, and TIME are all factors in whether it was a dead easy kid stuff "run", or a "luck" run by the best shottist who ever lived. In other words,something ANYONE could do, with his life bet upon it, or something that the top hand can NEVER repeat,reqardless of how many times he tries.
