Buckshot and birdshot: These commonly used shotshell ammo terms might cause confusion to a newcomer or even a more experienced shooter. So, what are birdshot and buckshot, and what’s the difference? Let’s settle it. 

Both birdshot and buckshot are catchall terms used to describe and categorize a wide variety of shotshell payloads. They’re built much the same way. Both feature a payload of loose pellets, often mixed with a buffering material that helps cushion the pellets from the forces of ignition. The pellets and buffer are held within a wad that separates them from the propellant. At ignition, the wad and pellets are pushed down the barrel and out the muzzle, where the shot separate from the wad and spread as they move downrange, forming a pattern.  

The main difference between buckshot and birdshot boils down to the size and number of pellets they hold. Buckshot is offered in 4 buck3 buck2 buck1 buck00 and 000, which range in diameter from .240 to .360 inch, respectively.  

Although birdshot is technically defined as size 7.5 or 8 pellets, it’s generally categorized as everything smaller than buckshot—regardless of whether the pellets are actually intended for shooting game birds or targets. This means everything from T shot steel used for geese to 9 shot pellets used for turkeys and clay target loads. Because of their large size, relatively few buckshot pellets can fit in the shotshell hull. For example, a typical 00 buckshot payload only holds nine individual pellets, while a No. 9 HEAVYWEIGHT TSS payload has more than 800.  

Federal offers birdshot payloads in hundreds of different options. Products include Prairie Storm, Premium UplandBlack CloudSpeed-Shok and many more. Federal’s buckshot loads are available in a smaller variety of loads. Some, like Federal Premium Buckshot and Power-Shok Buckshot are designed for targeting predators, deer and hogs. Others like Federal Premium Personal Defense Buckshot and Force X2 are meant for protection, primarily in the home. Some fall outside those categories altogether—like Shorty Shotshells, which are intended for targets.
