Well, I will be the one to say it first, 400 is beyond the range I would take a shot on a deer. Especially the size deer we have here in Alabama/Tennessee. Elk I will go that far but you have a much larger kill area. I have equipment that can do it but do not get to practice enough to feel 100% sure over 300. But to 300, I would take the shot everytime. I think that is called, knowing your limitations. JMHO TM
PS In Alabama it is hard to find a place to practice over 200 yards, with most ranges only 100, so that might have something to do with it too. :-)
