The effective range of any modern firearm probably exceeds the skill of the person squeezing the trigger. Unless you spend a lot of time practicing, even a 500-600 yard shot is beyond the ability of most hunters. I've never understood why anyone would want to shoot at game at those distances. I grew up in the wide open spaces of the west and the number of times I couldn't get closer that 300 yards could be counted on the fingers of one hand.
