I'm thinking about going to Bullseye indoor shooting range soon and i had a few questions. can i bring my own ammo like for a 9mm if i rent the gun there? I dont have a gun but i heard at some places maybe even bullseye that when you rent a gun you have to use their ammo. What would be the cheapest way to shoot one of their guns for an hour or so? Julio or Jaime, i know you guys have been there, any insight?
