What effect does deformation of the pellet have on the shot or pattern?

For this assignment, review the section in Applied Ballistics (SDI, 2016) titled “Understanding Shot” and conduct additional research as necessary. It may also be useful to review the section on “Shotgun Propellants”. Summarize the concept of “pellet deformation”. Consider the following: What are some of the reasons a pellet deforms when it is fired from a shotgun? What effect does deformation of the pellet have on the shot or pattern? What materials deform more readily than others? If there are some materials that do not deform, should shotgunners stick to only those types of pellet? What can be done to prevent deformation of shotgun pellets? What is “buffering” and how might that help?
