In this post I will be telling you the difference between six shot and eight shot shotgun shells. The main difference is the size of the pellets inside of the shell. The smaller the number, the bigger the pellets. The larger the number, the smaller the pellets. Another difference is the amount of gunpowder inside the shell and since there is more gunpowder, it has more recoil. One more difference that I can think of is that the smaller the shot the more pellets will fit inside the shell.
