Frequently Asked Questions
Will Rio Royal Star slugs work in my 12-gauge shotgun?
These are loaded in standard 2.75-inch shells, which chamber in any 12-gauge marked for 2.75 inches or 3 inches. Always verify your barrel markings before shooting—if your gun is marked 3.5 inches only, do not use 2.75-inch ammunition.
Are these slugs good for deer hunting?
Yes. The 1-1/8 ounce slug is a proven deer-hunting load, particularly effective at moderate ranges. Performance depends on your barrel type (rifled versus smooth bore) and shot placement—follow your state's regulations and practice at the range before the season.
What comes in each box?
Each box contains 10 rounds. Cases contain 25 boxes (250 rounds total), so you can buy by the box or stock up for the season with a full case.
How does the 1-1/8 ounce load compare to heavier slug options?
The 1-1/8 ounce slug is lighter than some magnum offerings, which means less recoil and faster target recovery between shots—ideal for hunting or sport shooting where follow-up accuracy matters.
