Re: Texas Residents
American Shooting centers has 100/200/300/400 and 600. Steel on the 600 yard line, and they also ask you to qualify for that distance.
Bayou Rifles is my preferred place as it is private, and there are 100/200/300/600-1000 yard lanes. Again, they ask you to qualify at 600+ unless you are with a member that has qualified.
Good luck in Baytown (grin).
