The number of pellets contained in the shell will depend on the size of the shot.
You don't mention what gauge. You will have to or else cut one open.
That depends on the size of the shot in the 3 inch shotgun shell,and the weight of the shot.
A 12-gauge shotgun shell typically contains multiple pellets, which are small, round projectiles inside the shell. The number of pellets in a 12-gauge 3" shell can vary depending on the specific type of shot being used, such as birdshot or buckshot. As a general guideline, a standard 12-gauge 3" shell with birdshot may contain around 1-1/8 to 1-1/4 ounces of shot, which can translate to roughly 200 to 300 pellets. For buckshot, there are typically fewer but larger pellets, with a 12-gauge 3" shell commonly holding around 8 to 15 pellets.
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).
Depends entirely on the gauge and size of shell. Can vary from 9-30
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.
OO Buck contains nine .32 sized lead balls.
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.
In fact, many products appear in forms of pellets. They can be used in many fields like animal feed pellets, bedding pellets and home heating pellets,etc.
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.
That would depend on the size of the wooden pellets.
The answer will depend on what the pellets are composed of and how they are being "consumed".
