Tyler, welcome to Austin. The historical miniature group in town is centered at Great Hall Games on N Lamar. Visit their forum at greathallgamers.org to arrange a Bolt Action game. Most of the users on this forum primarily play Warhammer 40k.

The historical guys usually meet on Sundays and sometimes Thursday night but we have a large Warmachine journeyman league going on then so space may be limited.
Feel free to contact me at [email protected]
Thanks
