Description
Rio's Star Team EVO line represents the top tier of their target ammunition engineering. These 12 gauge cartridges are built specifically for competitive clay shooting, with every component selected through Rio's proprietary development process and subjected to rigorous quality control. The result is ammunition that delivers consistent performance round after round.
What Makes Rio Star Team EVO Special
These shells push 1 ounce of #8 shot down range at 1280 feet per second, which sits in that sweet spot for clay target sports. The #8 shot size gives you dense pellet patterns while maintaining the velocity needed to break targets cleanly at extended distances. Rio engineered these with hard shot and precision components that work reliably in both pump-action and semi-automatic shotguns, so you're not limited by platform choice.
Pattern Density for Competitive Shooting
The 1 ounce payload with #8 shot creates tight, consistent patterns ideal for the demands of competition. Whether you're working trap, skeet, or five-stand sporting clays, you get the pattern uniformity that separates good days from great ones. Multiple shooters report that these shells break targets reliably inside 45-50 yards with minimal fatigue from recoil, making them solid for high-volume practice days where you might shoot several boxes without wearing yourself out.
Built for Clay Competition
Rio's commitment to clay shooting excellence shows in the Star Team EVO line. The manufacturer has earned Olympic medals and countless championship victories backing their ammunition, and these cartridges carry that same attention to detail. Each box contains 25 rounds of 2.75 inch shells, standard length that cycles smoothly in virtually all 12 gauge shotguns.

Frequently Asked Questions
What's the difference between Rio Star Team EVO and Rio's training loads?
The Star Team EVO is Rio's competition-grade ammunition with hard shot and premium components designed for serious shooters and tournaments. The training line uses softer lead and different wad materials pitched at a lower price point for high-volume practice. Both work in clay sports, but EVO is the step up if you're competing or want that extra consistency.
Will these Rio shells cycle smoothly in semi-autos?
Yes. The 1280 fps velocity and standard 2.75 inch shell length work reliably in semi-automatic shotguns. Users report clean cycling across most 12 gauge semi-autos without feeding issues. You'll get consistent performance whether you're running an over-under, pump, or semi-auto at the range or in competition.
Are these good for beginners or just experienced competitors?
While these are built to competition standards, they're accessible for any clay shooter. The #8 shot size is forgiving on pattern, and the 1280 fps velocity won't beat you up during a practice session. They break targets reliably, so whether you're learning or competing, you'll see good results if you do your part on the trigger.
How do Rio Star Team EVO shells perform at longer distances?
These shells deliver excellent pattern integrity and energy retention out to extended clay target distances. The 1 ounce of hard #8 shot maintains tight groupings, and multiple shooters confirm clean breaks even at the far end of typical clay shooting ranges. Rio's extensive testing ensures consistent performance across the full effective range.
