Depends entirely on the gauge and size of shell. Can vary from 9-30
The number of pellets contained in the shell will depend on the size of the shot.
Depends on the size of the shot, whether the shot is lead, steel or something else, the weight of the load and the gauge of the shell. A lead 1 oz load of #6 birdshot is about 225 pellets.
It depends on what kind of shot/cartridge you use. Shot, being the pelllets inside the cartridge, come in many different sizes, from 1mm to 9mm.
Not very many- between 3 and 5 pellets, depending on whether the shell is a 2.5 inch or a 3 inch. Many are 000 buck (known as triple ought) although some are in #4 buckshot. There is even one that is called 0000 buck, nearly .40 caliber.
The number of shots (pellets) in a 12 gauge 3-inch shell can vary depending on the specific type of shot and its size, but a common load for a hunting shell might contain around 1 to 1 1/8 ounces of shot, equivalent to around 170 to 200 pellets of size #7.5 or #8.
That depends on the size of the shot in the 3 inch shotgun shell,and the weight of the shot.
What size shell in legnth are you asking about?
Note: The shotgun does not have "bullets" it has shells which are the casings and generally pellets inside the casing (of different gauge's); the number of pellets vary according to the gauge or size of the pellet. The smaller the pellet, the more there are of them.
Depends on the guage and length of the shell, and the size of shot used. It may be as few as 3, (.410 Buckshot) or as many as several hundred (10 g birdshot).
7000
None. If you are asking how many pellets, the answer depends on the load. It could be anywher from less than 10 to a couple of hundred.
