This is where I used to do the Mile Shoot..Yep, completely agree. I've got a 400 yard limit just due to the variables involved and that I don't get a lot of practice at this sort of shooting any more. There's no place to set up such a range around here in the woods. I did used to have a lot of practice at 300 yards when I was a member of a club that had such a range.
From behind the firing point...
and the target ranges..
