Description
Winchester Super-X 20 Gauge Rifled Slug
The Winchester Super-X line carries a legacy built on quality and performance. Since 1922, these slugs have been engineered to give you consistent results without the guesswork. Each of these 20-gauge rounds features a full bore rifled slug with a hollow point design that improves both accuracy and sectional density compared to standard buckshot loads. The result is a precision hunting round that lets you take ethical shots at distances where buckshot simply won't cut it.
These shells fire at 1600 feet per second and carry 3/4 ounce of lead in a 2-3/4 inch shell. That velocity combined with the hollow point design generates the hard-hitting stopping power you need for deer, hogs, and similar game. The rifled slug design works in smooth bore barrels, rifled choke tubes, or fully rifled shotgun barrels, giving you flexibility across different shotgun platforms. Unlike some ammunition, Winchester's time-tested manufacturing processes ensure each slug is weighted to proper standards with consistent ejection from round to round.
What makes the rifled hollow point different is the improved accuracy and deeper penetration compared to buckshot. A single large projectile gives you a clean, consistent point of impact rather than a spread pattern. This is especially valuable if you hunt beyond 50 yards, where buckshot becomes unreliable. The full bore design works with smooth bores while still delivering the kind of precision that makes a real difference in the field.
This 15-round value pack makes it easy to stock up without overcommitting your budget. Each box gives you a reliable, proven slug load that won't let you down when it matters.

Frequently Asked Questions
Can I shoot Winchester Super-X rifled slugs through my smooth bore shotgun?
Yes, these slugs are specifically designed for smooth bore barrels. They'll also work in rifled choke tubes or fully rifled barrels. The full bore design improves accuracy and sectional density when fired through any of these configurations.
How do rifled slugs compare to buckshot for hunting?
Rifled slugs give you better range and accuracy compared to buckshot. Buckshot is effective up to about 50 yards in a tight pattern, while a rifled slug can take ethical shots out to 100-150 yards depending on your setup. The single large projectile penetrates deeper and gives you a consistent point of impact rather than a spread pattern.
What's the muzzle energy on these Winchester 20-gauge slugs?
The 3/4 ounce slug loaded to 1600 fps produces approximately 1865 foot-pounds of muzzle energy. That heavy projectile at velocity delivers reliable stopping power on medium game like deer, hogs, and similar-sized animals.
Why does the hollow point design matter on a rifled slug?
The hollow point provides superior stopping power and expansion upon impact. Combined with the full bore rifled design, it improves overall accuracy and sectional density, making these slugs more effective than conventional designs at extended hunting ranges.
