But have you been in a sales position for guns and ammo?
The thing is if it's your job you really should be more knowledgeable than the consumer.
Even those that have been shooting for over 45 years.
Heck, I have been living in house's with a furnace for over 50 years. It doesn't mean I know everything there is to know about furnaces, so when there is an issue I talk to someone that deals with furnaces for a living.
