Buckshot Pellet Sizes
All buckshot sizes listed above are standard lead shot sizes. The dimensions are listed in inches and millimeters. This buckshot pellet size chart is accurate for most lead pellet manufacturers – as the nominal size is used across the industry. For precise shotshell reloading, always use buckshot pellets with the same nominal pellet size and weight.
Note: #4 through #1 buckshot have the same naming scheme as smaller #4 through #1 pellets typically used for bird hunting (lead, steel, heavier than lead shot). These pellets do not have identical OD (outer diameters) and cannot be used interchangeably. Be aware that buckshot pellets are larger than small game pellets, and the smallest buckshot pellet (#4), is larger than F-shot steel.
Keep in mind, although all buckshot pellets range between 0.24” and 0.39” in diameter, not all buckshot manufacturers use the same processes, and therefore some dimensions can be slightly different. When exact pellet measurements are important, please check with the manufacturer for the latest dimensional information. See this chart for info on buckshot pellet counts per ounce.
