If you're looking for a non-competitive environment to practice in, the Kerrville range (Hill Country Shooting Sports) has a 500 yard range open every other weekend. It may or may not be open during the winter because it's run by a volunteer, James, but he's really helpful when it's open.
He can talk your ear off for hours, but sometimes seems to have an encyclopedic knowledge of firearms. He's also happy to spot for you, and give helpful hints.
It's usually not very crowded too, so it allows you to really hone your skills at your pace.
