Myself, i have never been so fortunate to have such a shot on deer. Years ago, i managed to get super close, and made the shot on a lunging, leaping Elk using a 4x scope. I often make this shot with my pellet rifle using a 4x scope and sorta consider it a 'long' shot. Right now i have three 4x scopes, and killed some deer with my Accura with a 4x scope mounted. Closest was about 40 yard, and furthest about 230 yard.

If your rifle and scope are 'right', when you bring the rifle to your shoulder, you will be aimed at the target. I find a 4x scope to be just fine at point blank range.
