FAQ: Maximizing Performance for the Best Slug for Smooth Bore 20 Gauge

Q1: Why is bore cleaning so important for achieving the best slug performance in a smooth bore 20 gauge?

A: A clean bore is critical because fouling (lead, carbon, plastic wad residue) can build up inside the barrel, creating inconsistencies. This buildup can alter the internal ballistics, leading to variations in muzzle velocity and decreased accuracy of your slugs. Regular cleaning ensures a consistent bore diameter and surface, allowing slugs to travel smoothly and predictably.

Q2: How do bore sighters, like the MidTen or GlobalPioneer, help with 20 gauge slug accuracy?

A: Bore sighters help you pre-align your sights or optics with the barrel’s axis without firing live ammunition. This gets you “on paper” quickly, meaning your first shots at the range will likely hit the target, even if not perfectly centered. This saves time and expensive slug ammunition during the zeroing process, allowing you to fine-tune your aim much more efficiently for optimal slug placement.

Q3: Can a Boresnake effectively clean a 20-gauge smoothbore for slug shooting, or do I need a traditional rod and brush?

A: A Boresnake is an excellent tool for quick and routine cleaning of your 20-gauge smoothbore, especially after a shooting session or when in the field. It effectively removes loose fouling and applies a light coat of oil in one pass. For heavy lead buildup or deep cleaning, particularly if you’re experiencing decreased slug accuracy, a traditional cleaning rod with a dedicated phosphor bronze brush and patches will offer a more thorough scrubbing power.

Q4: Are there any specific cleaning agents or lubricants recommended when maintaining a 20 gauge for slugs?

A: For cleaning, look for gun cleaning solvents specifically designed to remove lead, carbon, and plastic fouling, as all three can accumulate in a smoothbore from slug and wad use. Products like Hoppe’s No. 9 or specialized lead removers are effective. For lubrication, a high-quality gun oil or CLP (Cleaner, Lubricant, Protectant) is essential to protect against corrosion and ensure smooth action. The Clenzoil Field & Range solution included in some kits is a great example of an all-in-one option.

Q5: How often should I clean my 20-gauge smoothbore shotgun when using slugs?

A: The frequency depends on your shooting volume and conditions. Generally, it’s a good practice to perform a light clean (e.g., with a Boresnake) after every range session or hunt where slugs were fired. A more thorough cleaning with a rod and brush should be done every few hundred rounds, or if you notice a significant decrease in slug accuracy or have been shooting in harsh conditions. Consistent cleaning is key to reliable 20 gauge smoothbore performance.

Q6: What’s the benefit of using a specific phosphor bronze brush for a 20-gauge shotgun over a general-purpose brush?

A: A specific phosphor bronze brush for a 20-gauge shotgun is sized precisely for the barrel’s diameter. This ensures that the stout bristles make maximum contact with the bore’s surface, effectively scrubbing away lead, carbon, and plastic wad fouling without being too loose or too tight. A general-purpose brush might not provide the same optimal scrubbing power or fit, making the cleaning process less efficient and potentially leaving more residue behind, which can impact slug trajectory.
