Description
Fiocchi's Hyperformance Hunt line brings serious varmint hunting capability to your .223 with the Barnes Varmint Grenade bullet. This 50 grain load delivers a muzzle velocity around 3300 fps, producing flat shooting trajectories that make it easy to dial in distance to your target.
The Varmint Grenade bullet is where this round really stands out. Built with a frangible copper-tin powdered metal core surrounded by a gilding metal jacket, it fragments rapidly on impact to eliminate target without over-penetration. That means less meat damage on small game and predators while still delivering devastating terminal performance. The bullet holds together at high velocities through fast-twist barrels, then breaks apart violently on impact for quick, clean kills.
Fiocchi Hyperformance Construction Quality
Fiocchi focuses on precision-formed brass cases paired with reliable primers and carefully selected clean-burning powder. Their Ozark, Missouri facility produces ammunition to exacting standards, and you'll notice the quality the moment you handle these rounds. Each cartridge is consistent in appearance and construction, with no loose or undersized cases. The boxer-primed brass is reloadable, giving you the option to stretch your dollar further if you're into handloading.
Barnes Varmint Grenade Ballistics
The 50 grain weight strikes a balance between velocity and accuracy. It's light enough to push fast from the .223 case, but heavy enough to carry energy downrange. The lead-free construction makes this round suitable in areas with environmental concerns, and it delivers the precision needed for both varmint control and pest hunting from prairie dogs to coyotes. Just note that the 50 grain Varmint Grenade needs a faster twist barrel, ideally 1 in 10 or faster, to stabilize properly.
Packed 20 rounds per box with 10 boxes per case, this ammunition is ready to work.

Frequently Asked Questions
What twist rate does my barrel need for the 50 grain Barnes Varmint Grenade?
The 50 grain Varmint Grenade requires a 1 in 10 twist or faster to stabilize properly. Slower twist barrels won't spin the bullet enough for stable flight, which will hurt accuracy. AR-15s with 1 in 7 or 1 in 8 twist barrels work great, but traditional bolt guns with 1 in 12 twist may struggle.
Is this ammunition suitable for reloading the brass cases?
Yes. Fiocchi uses boxer-primed brass cases that are designed to be reloadable. The brass is quality material, and many reloaders prefer Fiocchi brass for its consistency and durability. Just inspect cases before reloading as you would with any ammunition.
What makes the Barnes Varmint Grenade different from a standard hollow point?
The Varmint Grenade uses a frangible copper-tin powdered metal core that fragments rapidly on impact, rather than a traditional lead core. This design produces instant expansion on small game while limiting penetration, which reduces pelt damage and minimizes over-penetration on varmints and predators.
Is this lead-free ammunition suitable for California hunting?
Yes. The lead-free construction of the Barnes Varmint Grenade makes this a good option for areas with lead ammunition restrictions. Check your local regulations to confirm what types of ammunition are allowed in your area.
