buckshot was used to hunt deer in the old days.(( hint the name). mostly double aught (.00) lead balls in the shell.. usually only 6 -8 lead pellets in the shell..
Buckshot is still used to hunt deer currently. There are several sizes of popular Buckshot. My favorite is Number four buckshot in a three-inch 12 guage, with 41 .24 caliber pellets...it is like a swarm of bees. Even the 2-3/4 inch 12 guage has 27 pellets of Number 4 buckshot. Number 3 Buckshot is popular with 20 guage deer hunters.
