Description
The Rio Star Team EVO has earned its reputation among clay shooters for one simple reason: it works. This 12 gauge load packs 1 1/8 oz of #7.5 shot into a 2.75-inch shell, giving you the proven combination that breaks targets reliably across trap, skeet, and sporting clays disciplines.
#7.5 shot sits at the sweet spot for clay shooting. It carries more energy per pellet than #8 and #9, making it the choice for longer crossers and when you need a bit more break potential at distance. Whether you're shooting tight patterns on close presentations or opening up for those 40-yard birds, this load handles it. Many competitive shooters keep a box of #7.5s on hand for exactly those situations where you need a touch more power without sacrificing pattern density.
What Makes Rio Star Team EVO Stand Out
Rio built their reputation on controlled manufacturing. They handle everything in-house, from the powder to the primers to the shot itself. That vertical integration means every component is quality-checked before assembly, and it shows in how consistently these shells pattern. You're not guessing what you'll get when you crack open a box, and that consistency matters when you're working to improve your game.
Performance on the Course
With a standard muzzle velocity of 1200 fps, the EVO generates enough energy to break clays decisively while keeping recoil manageable for high-volume practice. The clean-burning powder minimizes fouling, so your gun stays cleaner longer during those 100+ round sessions. Each box contains 25 shells, and buyers typically purchase full cases of 10 boxes for extended practice without resupplying constantly.
Whether you're at the gun club for league shoots or putting in solo practice hours, the Rio Star Team EVO delivers the reliability and value that keeps you coming back.

Frequently Asked Questions
What shooting disciplines is the Rio Star Team EVO best suited for?
The #7.5 shot size makes this load ideal for trap, skeet, and sporting clays shooting. Many clay target shooters favor #7.5 for longer crossing shots and when they need a bit more pellet energy at distance compared to #8 or #9. It's a versatile choice that works well in all three major clay disciplines, especially in sporting clays where varied target distances require solid break potential.
Will Rio Star Team EVO shells cycle reliably in my semi-automatic shotgun?
Yes. The 1200 fps velocity provides enough chamber pressure to cycle modern semi-automatic shotguns smoothly without excessive recoil. Many shooters report that these shells function reliably in both semi-auto and over-under designs, making them a dependable option for high-volume practice when you're moving between different shotgun types at the range.
How does Rio Ammunition control quality in their Star Team EVO line?
Rio manufactures every component of these shells in-house, including the powder, primers, hulls, and shot. That means they control the entire supply chain, resulting in consistent pattern performance and reliable ignition. Their quality control standards ensure that each box performs as expected, which matters when you're working to improve your scores or fine-tune your gun's performance.
Is #7.5 shot the right choice for my clay shooting, or should I try #8?
That depends on your shooting style. #7.5 carries more energy and works great for longer distance targets or when you want a margin of safety on break potential. #8 delivers a denser pattern and is preferred by many skeet shooters and for closer presentations. Many shooters keep both sizes on hand and choose based on the course layout and target distance that day.
