Description
When you're serious about varmint control, ammunition matters. Federal Premium V-Shok loads cut through the noise and deliver what counts. Each round pairs a 30-grain Speer TNT hollow point bullet with Federal's tested components for ballistics you can count on shot after shot.
Speer TNT Design Meets Rimfire Velocity
The Speer TNT bullet's thin jacket design is built to fragment on impact, creating the kind of reliable expansion that works even at rimfire velocities. That's the whole point with varmint work. You're not looking for deep penetration on prairie dogs or ground squirrels. You need rapid disruption. This Federal loading delivers it at 2200 feet per second, bringing 322 foot-pounds of energy downrange. For hunting ranges from 25 to 125 yards, this is the kind of performance that gets the job done.
Quality Components for Consistency
Federal doesn't cut corners on components. The primers receive more frequent inspections for dimensional tolerances and charge weight than standard ammunition. The powder is specially formulated to Federal's stringent specs and represents the cleanest-burning grades available. This isn't flashy marketing talk. It translates to consistent velocities between rounds, predictable bullet performance, and the kind of reliability you depend on in the field. Brass cases keep things clean for your rifle too.
Practical Rimfire Performance
The 30-grain weight sits at the sweet spot for .22 Magnum ballistics. It's the same weight professional varminters reach for because it balances velocity with energy delivery. Federal's V-Shok line has earned its reputation because it works where it matters. Accuracy remains flat enough for confident shot placement at distance, and the TNT design creates enough terminal performance to drop varmints without pass-throughs that cause unnecessary damage to your hunting area. Each box holds 50 rounds of non-corrosive, new production ammunition.

Frequently Asked Questions
What's the effective range for this Federal .22 WMR ammunition?
The flat trajectory of this 30-grain load stays true out to about 125 yards with proper rifle accuracy. Skilled shooters can extend that to 150 yards, but varmint hunting with .22 Magnum works best in the short to medium range. Beyond 125 yards, you start fighting velocity drop and energy loss.
How does the Speer TNT bullet perform on impact?
The TNT's thin jacket is designed to fragment quickly when it hits. On small varmints, this creates rapid expansion and disruption rather than deep penetration. This performance shows up consistently across the velocity range of a rimfire rifle, making it reliable from 25 to well over 100 yards where terminal performance matters most for quick, humane kills.
Is this Federal Premium ammunition reliable in semi-auto rimfire rifles?
Yes, this ammunition is new production, non-corrosive, and built to Federal's component standards. Many shooters report this load cycles cleanly in AR-pattern rimfire uppers and other semi-auto platforms. That said, like any rimfire ammunition, cycling depends on your specific rifle's tolerances and tuning.
How does Federal Premium V-Shok compare to other .22 Magnum varmint loads?
The Speer TNT offers a solid middle ground. It delivers faster, more reliable fragmentation than harder-jacketed bullets and comes with Federal's quality control behind every component. Some shooters prefer polymer-tipped rounds for even flatter trajectories at distance, but for consistent varmint performance in the 25 to 125-yard range, the TNT is a proven choice.
