Description
The Rio Star slug is built for shooters who want straightforward, dependable performance without overspending. This 12 gauge load pairs a standard 1-1/8-ounce rifled slug with a 2.75-inch hull, delivering 1410 feet per second of velocity. The rifled slug design helps stabilize the projectile as it travels through smoothbore barrels, which means you get better on-target performance out of the gate without needing special rifled barrels or sabot ammunition.
What Sets the Rio Star Slug Apart
Rio has built a strong track record for consistent ignition and clean-burning powder formulations. The brass-head construction feeds smoothly through most shotgun platforms, whether you're running a pump, semi-auto, or break-action. You get consistent performance shot after shot, which matters whether you're working the range or depending on the gun to deliver.
Design for Real-World Use
The 1-1/8-ounce load strikes a practical balance. It delivers stout energy and predictable trajectories at typical hunting and defensive ranges, while the weight keeps recoil manageable enough for follow-up shots. The 1410 fps velocity is strong without being unnecessarily hot. Each box contains ten rounds, making it convenient for practice sessions, training days, or field use without buying more than you need at once.
Built to Cycle Smoothly
Rio's Star line is known for reliable cycling across a wide range of shotgun types. The ammunition feeds without drama and ejects cleanly, so you can focus on your shooting rather than managing feeding issues. That reliability comes from their control over the entire manufacturing process, which includes everything from hulls and primers to powder and projectiles made at their facility.

Frequently Asked Questions
What type of shotgun should I use with Rio Star slugs?

What's the effective range for this Rio slug load?
With basic bead sights, you can expect reliable accuracy out to around 50 to 75 yards.

Performance beyond that depends on your specific shotgun, your shooting skills, and your sights or optics.
How does this compare to other slug brands?
