As a firearms expert with extensive knowledge in ballistics and firearm mechanics, I'm often asked about the compatibility of different ammunition types with various firearm configurations. The question at hand pertains to the use of a "slug" in a shotgun barrel, specifically one with a "full choke." Let's delve into the specifics.

Firstly, it's important to clarify what a "slug" is. A shotgun slug is a single projectile that is fired from a shotgun, designed to offer the accuracy and range of a rifle round but with the versatility of a shotgun. They come in different lengths, typically 1", 1 1/4", 1 1/2", 2", and 3", with the 1 1/4" being the most common.

Now, onto the "full choke." A choke in a shotgun barrel is a constriction that controls the spread of the shot or the trajectory of a slug. A "full choke" is one of the tighter constrictions, designed to keep the shot or slug tightly grouped over a longer distance. This is particularly useful for hunting or precision shooting.

**Shooting slugs through a full choke barrel:**


1. Compatibility: Shotguns can safely shoot rifled slugs through a fixed full choke. The tighter constriction helps maintain the slug’s velocity and accuracy over a longer range. However, it's crucial to match the slug's length with the barrel's length and choke to ensure optimal performance.


2. Barrel Length: The reference to a 28" barrel suggests that the user is considering a shotgun with a relatively long barrel, which is beneficial for shooting slugs due to the increased velocity and accuracy that a longer barrel can provide.


3. Choke Type: While a full choke is suitable for slugs, the mention of a "cyl or Imp cyl choke" indicates that a cylinder or improved cylinder choke might also be considered. These chokes have less constriction than a full choke and could be used for shorter range shots where a tighter pattern is not as critical.


4. Slug Size: The comparison between a 3" slug and a 2 3/4" slug suggests that there might not be a significant advantage to using the longer slug unless the range and shooting conditions warrant it. The choice of slug size should be based on the intended use and the capabilities of the shooter.


5. Safety: It is generally safe to shoot rifled slugs through a full choke barrel, but always ensure that the shotgun and ammunition are compatible and that the shooter follows all safety protocols.


6. Performance: The performance of a slug when fired from a shotgun barrel with a full choke will depend on various factors including the slug's design, the barrel's length, the choke's constriction, and the shooter's skill.

7.
Maintenance: Regular cleaning and maintenance of the shotgun barrel are essential, especially when shooting slugs, as they can leave more residue compared to shotshells.

In conclusion, shooting a slug through a full choke barrel can be done effectively and safely, provided that the correct slug size is used and the shooter is aware of the nuances of using a full choke. Always consult the shotgun and ammunition manufacturer's guidelines to ensure safe and effective use.
