I have no problem shooting out to 150 with my .44 mag/red dot site,thats when shooting at a known distance at a stationary target...but just like the tables Gary put up,....I can't tell the difference with my eye sight between 150 and 200 yards and that's a lot of difference in impact point between those two distances when hunting,so I try to make sure I keep my .44 mag. shots to 100 yards or below on game.
