Description
CCI brings together decades of rimfire expertise with the Maxi-Mag TNT, a no-nonsense .22 WMR load designed around one thing: varmint control at distance. This isn't plinking ammo. The 30-grain TNT hollow point sits on the aggressive end of the .22 WMR spectrum, traveling at 2200 feet per second with a ballistic coefficient of 0.088. That combination delivers a flat, predictable arc and serious impact energy on target.
TNT Bullet Design
The TNT isn't just another hollow point. CCI engineered this projectile with an extremely thin jacket and strategic longitudinal flutes that cause the bullet to shed velocity and expand dramatically on impact. It's based on proven Speer Gold Dot technology, which means the expansion is controlled but aggressive. For varmint hunting, that's exactly what you want. Small animals don't require deep penetration, and the TNT's design capitalizes on that reality to maximize tissue damage and energy transfer.
Built on Proven CCI Standards
The Maxi-Mag TNT package uses the same quality components that made CCI's name in rimfire ammunition. Noncorrosive rimfire primers, clean-burning propellants, and precision-loaded brass cases keep your rifle running smooth while delivering the velocity consistency needed for accurate, repeatable shooting. The straight, concentric brass cases feed reliably through rifles and revolvers alike, and the packaging comes in a reusable 50-round box with a convenient dispenser lid.
Practical Performance
This load shines at the distances where .22 WMR was designed to work, typically 50 to 100 yards on targets ranging from prairie dogs and groundhogs to coyotes and fox. The flat trajectory means less hold-over adjustment, and the velocity gives you room to work beyond typical .22 LR effective ranges. Field reports consistently show tight groups and explosive terminal performance, making the TNT a solid choice when you need results.

Frequently Asked Questions
What makes CCI Maxi-Mag TNT different from other .22 WMR hollow points?
The TNT uses an extremely thin jacket with strategically placed flutes to promote aggressive, reliable expansion on impact. This design traces back to Speer Gold Dot technology and is specifically engineered for varmint hunting. The combination of the TNT bullet with CCI's proven Maxi-Mag velocity platform creates a load that balances speed, expansion, and consistency.
Is this ammo suitable for both rifles and revolvers?
Yes. The Maxi-Mag TNT feeds reliably in both .22 WMR rifles and revolvers. That said, your individual firearm may perform better with certain loads, so it's always worth checking what feeds and groups best in your specific gun.
What distance should I expect to use this ammo effectively?
The Maxi-Mag TNT is designed for varmint hunting at typical .22 WMR distances, roughly 50 to 100 yards depending on your target and rifle setup. The 2200 fps velocity and flat trajectory give you good performance at range compared to standard .22 Long Rifle, but barrel length and sight setup will affect your specific results.
Does the reusable box come with a dispenser?
Yes. The 50-round box features a dispenser lid, which makes it convenient to feed rounds one at a time without spilling them around your bench or range bag.
