Agreed, it depends on the gun. Roger vaquero is six. I also have the opinion of a soldier, load all you can, know the state of your weapon.

The Game and parks officer there thanked me later for raising the point. The instructor had shot himself twice, and suggested this as a way to make sure you “knew” the gun was loaded.
