As a firearms expert with extensive experience in the field, I've spent considerable time understanding the mechanics and usage of various firearms, including the nuances of shooting slugs from shotguns. The question of whether a slug can be effectively shot out of a modified choke is an interesting one, with a variety of factors to consider.
Firstly, the term "modified choke" refers to a specific constriction level in a shotgun barrel that is less restrictive than a full choke but more restrictive than an improved cylinder. This constriction is designed to slightly narrow the shot pattern, which can be beneficial for certain types of hunting or shooting sports. However, when it comes to shooting slugs, the dynamics change significantly.
Slugs are different from shot pellets in that they are single, solid projectiles rather than a multitude of small pellets. This means that the constriction of the choke does not have the same effect on a slug as it would on a shotshell full of pellets. The purpose of a choke in a shotgun is to control the spread of the shot, but since a slug is a single projectile, the choke's primary impact is on the velocity and trajectory of the slug.
The statement that "there are even 'rifled' tubes available" is accurate. Rifling refers to the spiral grooves cut into the bore of a gun barrel, which imparts a spin to the projectile, stabilizing it in flight much like a rifle bullet. This can be beneficial for shooting slugs as it can improve accuracy over longer distances.
When considering the best choke for shooting slugs, it is indeed advisable to use a choke that offers the least constriction. This is because a less constricted barrel allows the slug to maintain its velocity for a longer period, leading to flatter trajectories and potentially greater accuracy. Improved cylinder, skeet, and cylinder chokes are all suitable for this purpose, as they provide minimal constriction.
On the other hand, full choke barrels are generally not recommended for shooting slugs. The high degree of constriction in a full choke can significantly reduce the muzzle velocity of the slug, leading to a rapid drop in trajectory and decreased accuracy. This is particularly problematic at longer ranges where maintaining a flat trajectory is crucial for hitting targets effectively.
In conclusion, while it is possible to shoot a slug from a modified choke, it is not the most ideal setup. For optimal performance and accuracy, it is best to use a shotgun with a less restrictive choke, such as an improved cylinder, skeet, or cylinder. Rifling can further enhance the performance of a slug by stabilizing it in flight, making it an attractive option for those looking to maximize the effectiveness of their shotgun when shooting slugs.
