For example, someone hunting small, fast birds would generally use an improved cylinder or modified choke, which creates a broad shot pattern that spreads quickly at close ranges. Conversely, someone hunting a larger, less mobile bird, such as a turkey, would select a full choke, which concentrates the shot in a tighter pattern. Pellet size also varies based on the size of the game. The chart below suggests choke and shot sizes for a variety of game. It is intended only as a guide—choice of choke and shot size may vary depending on ammunition, target distance, and hunting conditions.
