Good day to try and get dope out to 500?
You should be ready with a drop chart out to 500 yards, but it's a good way to confirm or true up your dope. They don't want people shooting over the top of the berm at 500 if you have no idea what elevation you need.
If you don't have any estimates for that range there are usually plenty of people there to help you calculate your elevations or holds. You can confirm at the shorter distances and work out to the 500. I will have my magnetospeed if you need to get some velocity data.
