I took the shotgun class at Rangemaster. I don't remember the instructors. There were three. They told me the class started at 9. I called to confirm the class time because the internet had a different time and was told 9. I got there at 9 along with about half the class and they said the class started at 10. I thought that the instructors were jerks.
The class itself was good but I just like the Range USA. They can teach you without being a donkey about it. The class at Range USA had fewer people in it so things move along a lot faster.
FYI I have not taken the carry permit class so I can't say either way on that class.
