The Hoppe’s Boresnakes (Clam E/F, 24033D, Viper) all excel in rapid, one-pass barrel cleaning, with the Viper offering enhanced scrubbing power.

Finally, don’t overlook specialized tools like the Birchwood Casey Bore Mop, which is perfect for applying lubricants, and the Otis Technology Bore Brushes, offering versatile and dense scrubbing options for deep cleans.

Final Verdict

When I think about getting the “best” performance out of any slug in my 20 gauge smooth bore, it’s really about consistency – and consistency comes from a well-maintained and accurately sighted firearm. If you’re looking for speed and convenience in cleaning, any of the boresnakes, especially the Hoppe’s Viper for extra scrubbing power or the 24033D for its case, are excellent choices.

Best Slug for 20 Gauge Smooth Bore: Your Questions Answered

Q1: How does proper cleaning affect the accuracy of slugs fired from a 20 gauge smooth bore?

A1: Proper cleaning is crucial for slug accuracy. Fouling, lead buildup, and residue inside the barrel can create inconsistencies in slug flight, affecting velocity and trajectory. A clean, smooth bore allows the slug to travel unimpeded, leading to more consistent and accurate shot placement, regardless of the slug type.

Q2: Are bore sights really useful for a 20 gauge smooth bore, especially for shooting slugs?

A2: Absolutely! Bore sights are incredibly useful for initial sighting-in. They allow you to get your scope or iron sights roughly aligned with the bore without firing a single shot. This saves a significant amount of ammunition and time at the range, making the final zeroing process with live slugs much quicker and more efficient.

Q3: What’s the main difference between a boresnake-style cleaner and traditional bore brushes for a 20 gauge?

A3: Boresnake-style cleaners (like Hoppe’s Boresnake or Envistia Mall Bore Rope) offer a quick, all-in-one cleaning solution, combining a brush, scraper, and swab in a single pass. They are excellent for fast field cleaning and regular maintenance. Traditional bore brushes (like Otis Technology’s) are typically used with a cleaning rod and patches for more thorough, focused scrubbing and can be more effective at removing heavy, stubborn fouling with specific solvents.

Q4: Can I use these 20 gauge cleaning products for other shotgun gauges?

A4: No, it’s critical to use gauge-specific cleaning tools. A 20 gauge boresnake or brush is designed for a 20 gauge barrel diameter. Using an incorrect size can either be ineffective (too small) or damage your barrel (forcing a too-large cleaner). Always match the tool to the gauge.

Q5: How often should I clean my 20 gauge smooth bore if I’m primarily shooting slugs?

A5: The frequency of cleaning depends on how much you shoot. For casual use, a thorough clean every 50-100 rounds or after every few outings is a good rule of thumb. If you shoot slugs extensively, especially lead slugs which can cause more fouling, a quick boresnake pass after every session and a deep clean every 50 rounds will help maintain peak performance and prevent significant lead buildup.

Q6: Why is applying lubricant or oil after cleaning important for a 20 gauge shotgun?

A6: After cleaning, the bore is stripped of any protective oils. Applying a light, even coat of lubricant or gun oil (which a bore mop is perfect for) is essential to prevent corrosion, especially if the gun will be stored for a while. It also helps reduce friction for the next slug that travels down the barrel, contributing to consistent performance and protecting the firearm’s longevity.

Q7: Do any of these cleaning products also help with choke tube maintenance for a 20 gauge?

A7: While the primary focus of these products is the barrel bore, a boresnake or a small bore mop can certainly be used to quickly clean the inside of your choke tube if it’s removed from the barrel. For stubborn fouling or plastic wad residue in choke tubes, dedicated choke tube brushes or a more vigorous cleaning with solvents might be needed in addition to these general bore cleaners.
