What's the best way to carry extra shotshells?

I've been asked many times, for the best way to carry extra shotshells on a shotgun. Granted there are a few options. Everything from a shell bag, shells in your pockets, and fixed shell carriers (to name a few). Those options work. However, for me there is a simple and highly effective way to keep additional ammo with your shotgun..."shotshell cards".

There is nothing better than stripping an empty card off your frame and slapping on a fully loaded one!

In this video we show how it's done and discuss why it's preferable to fixed shell carriers.
