12 Pellets - 00 Buck - 1325 fps 15 Pellets - 00 Buck - 1210 fps 10 Pellets - 000 Buck -1225 fps I am putting an ammo order together to replace all my carry and home defense ammo. The handgun ammo is an easy choice, but I have no idea on the shotgun ammo. By the way those are my only choices for Federal 12ga 3" shells from that site. Which would you choose and why? Thanks everyone, the order has been placed. I went with the 15 pellet 00 Buck. It was a tie at the time of ordering, so I went with what more people answered, which was the more pellets the better.
