Where the rounds on the display cards come in handy is when you are trying to find what does or does not shoot well out of your smoke pole. It would suck to buy 50 or 100 of a type bullet that your gun does not like.

Most folks try out what their friends shoot, but if you dont have anyone that will let you shoot a little bit of their favorite bullet/sabot combo you dont have to buy a lot to try them out.

After you know what you want to shoot or what shoots best in your weapon, then buy in bulk.

You can buy most any of the major brands in bulk and save a lot compared to the price that you would pay for small quantities on the display cards.
