ss1, I live in Spring Branch (west Houston) and shoot at Hot Wells (290/Barker Cypres), a small family owned range. About $6 to shoot plus tax. Have to sit down to shoot there, otherwise no complaints.
Others like the American Range at George Bush Park (Westheimerand Hwy 6). It seems "too busy" there for me and I haven't been there to shoot, but plan to try it some day with some friends.
Now, do you know of any ML clubs in our area? Sam Houston Muzzleloaders has cloed down. I can't beleive that here aren't any clubs in or near the fourth largest city in the nation.
