Holy crap, that's a long ways.
I belong to a private range where every day I can shoot to 300 yards, and then some certain events can shoot to 500. Have access to land a couple hours away where I could shoot as long as I wanted to but haven't taken advantage yet. I'd like to get to a point where I'm killing most prairie dogs under 400 yards before I buy more stuff and start pushing the distances.
As it is now I'm working up a load for my sporter 25-06 and 26 rounds in one session was enough to have my shoulder throwing in the towel.
