It seems there might be a typo or error in the brand name “FETTER” as I couldn’t find specific information on ammunition produced by that name in my database up to my last knowledge update in September 2021. However, I can provide some general information about 12-gauge rifled slugs:12-gauge rifled slugs are shotgun projectiles designed for hunting and shooting sports. Here are some key details about them:

1. Gauge: The term “12-gauge” refers to the internal diameter of the shotgun’s bore. It is a common and widely used shotgun gauge.
2. Type: Rifled slugs are designed to be fired through smoothbore shotgun barrels. The slug itself is rifled, meaning it has spiral grooves on its surface, which helps stabilize the slug in flight and improve accuracy.
3. Length: The “2.75 inches” refers to the length of the shotgun shell. It’s important to use the appropriate shell length for your shotgun as specified in the firearm’s manual.
4. Weight: “1-1/8 oz” indicates the weight of the slug. In this case, it’s 1 and 1/8 ounces. Slug weight can vary, and it affects factors such as recoil and terminal ballistics.
5. Purpose: Rifled slugs are typically used for hunting large game at close to medium ranges. They are particularly popular for deer hunting. The rifled design enhances accuracy, making them effective at moderate distances.
6. Case: Cases of shotgun ammunition typically contain multiple shotgun shells, often 5, 10, 25, or more shells, depending on the packaging and the manufacturer’s specifications.
7. Legal Considerations: Always be aware of and comply with local, state, and federal laws and regulations regarding the purchase, possession, and use of ammunition for hunting and shooting sports.

If you have specific questions about “FETTER” ammunition or need more detailed information about rifled slugs, it would be advisable to check with local firearms dealers or online retailers for the most up-to-date information, as well as to ensure compatibility with your shotgun.
