They are having precision matches in Marble Falls also. Copperhead shooting center. They just hosted the 3 gun precision match a couple of weeks ago. There is also a long range match in Orange Grove. I have not been to it yet. I looked into to going to Bayou Rifles in Rosharon but they do not allow shooting steel.
As far as tearing up steel with a 25-06, I would not worry about it. Most matches are capping bullet size at 30 cal. There is a long distance rifle range being built in Fulshear. Not sure if they will be doing matches.
