Just left range today. The method using the sled of aiming at o taking a shot. Continue to aim at o but move your reticles to be POI of you last shot. Set POA back to o should be pretty close if you didn't change you POA. Down side for me is I don't have tactical turrets, mine require using a nickle or screwdriver as its just a little recessed slot. So it's impossible to keep POA (look through the scope) and adjust sites at the same time.

Long sorry short The Nikon 3-9x40 kit scope is inadequate for my needs. Will upgrade to better scope.
