Pawnee would be fun... I'm pretty sure we could set up steel targets as far as you want or to your hearts content
Another thing to is... don't worry about blowing through so much ammo. I usually bring 100 rounds or LESS for long range shooting. I also bring my .22 bolt gun for shit's and giggles.
Ahh yes... I'm down for another trip down there after this Raton match.
