Re: Setting up a range.....
Where in Texas are you? Do you have a limit on how many berms your gonna have? Are you limited also on the width that you have for the range? More details would be nice.
Me, I'd do paper/stands only at 50, 100, 150, & 200. I'd berm at 300 and then every 100yds after that of your limited on width. If not, I'd berm 300, 400, 500, 550, 600, 650, 700, 750. I'd stagger the berms so that all the "x50's were to the left and all the "x00's" to the right or vice versa.
I'd have some "Know your limitations" steel set up at 300/400 yards. Also, have atleast 2 targets per berm with one of them being a 1-2 MOA steel target. It's nice to have something smaller than a full size silhouette to aim at. Hitting a full size target at 500-700 yds isn't really a challenge to some folks. A 1 MOA circle/diamond at 750 can give you a challenge sometimes if you have wind to contend with.
These are just ideas.
