If you shoot a 20 gauge, you already know Rio Royal Buck ammunition. These shells have become a go-to load for people who want serious performance without the premium price tag. Each round fires nine #1 buckshot pellets at 1345 feet per second, which puts more projectiles downrange than standard 00 buck while offering better penetration than the smaller #2 and #3 sizes most commonly available in this gauge.
These shells deliver solid patterns at typical hunting and defensive ranges. Users consistently report tight groupings and excellent behavior through pump and semi-auto shotguns. The #1 buckshot size works well on whitetail-sized game and provides more stopping authority than lighter loads. Rio manufactures these in Spain using their own components, which gives them control over the entire production process from brass to pellets to wads.
Finding a quality #1 buckshot load in 20 gauge isn't easy. Most ammunition makers stick with #2 and #3 for this gauge, but #1 gives you larger projectiles with deeper penetration. The 1 1/8 ounce payload delivers real knockdown power while staying manageable. These shells use rolled crimps and high brass construction, built to handle the pressures of a hard-hitting load without compromise.
Twenty-five rounds per box give you enough to pattern your gun or work up a supply. Rio packages these shells consistently, so you can trust what you're getting from one box to the next. They fire reliably, pattern well, and cost considerably less than boutique defensive ammunition or hunting-specific loads from premium brands.
#1 buck offers larger pellets than #3 and delivers more potentially effective wound trauma than #00 buck when the pellet count is factored in. It's the largest buckshot size available for 20 gauge and provides better penetration than smaller shot sizes, making it a solid choice for hunting medium-sized game or defensive scenarios where you want maximum per-pellet energy.
These shells have a rolled crimp and run slightly longer than standard 2.75-inch shells, which can occasionally affect magazine capacity in tube-fed shotguns by reducing the round count by one. They cycle reliably in most pump and semi-auto shotguns, though some users report potential feeding issues in specific shotgun models. Testing them in your gun is always the smart move.
Rio Royal Buck kicks noticeably more than light target loads, but that extra recoil comes with the extra power. Users generally describe it as manageable in 20 gauge shotguns, though the harder kick is part of what makes these shells effective. The 20 gauge recoil impulse is still considerably milder than comparable 12 gauge loads.
Yes, Rio Royal Buck uses reloadable brass cases with Boxer primers, so you can reload them once fired. The high brass construction holds up well to reloading, making these a good long-term investment if you're into handloading shotshells.
