Description
If you're looking for rimfire ammo that punches above its weight class, Federal Game-Shok .22 WMR is a solid choice. With a 50-grain jacketed hollow point bullet moving out at 1530 feet per second, these rounds deliver 260 foot-pounds of muzzle energy. That's enough punch for small game hunting and varmint control while staying manageable in recoil. The brass cases are non-corrosive and designed to feed reliably through both rifles and semi-auto firearms.
What the 50 Grain Game-Shok Does Well
The jacketed hollow point design balances expansion with penetration—critical for taking down game cleanly without excessive meat damage. Customer feedback consistently notes no feeding issues, and the rounds perform well out to typical small game ranges. These work equally well for squirrel and rabbit hunting as they do for casual target practice. The cartridge carries noticeably more energy than .22 LR out to distance, making it practical for hunting scenarios where precision matters.
Why Choose This Weight and Bullet Style
The 50-grain load sits in the middle of the .22 WMR spectrum. It gives you more knockdown power than lighter 30-grain options while maintaining flatter trajectory and faster velocity than heavier hunting rounds. The hollow point expands on impact for quick, ethical kills on game-sized targets. For someone who wants a single .22 WMR round that handles both hunting and range time, this weight is a practical all-arounder.
Federal built the Game-Shok line to be affordable without skimping on reliability. You get 50 rounds per box with consistent brass casings and reliable primer ignition. The load generates enough energy to hold its own, yet recoil remains light enough that you can focus on accuracy.

Frequently Asked Questions
What is .22 WMR ammo best used for?
.22 WMR is ideal for small game hunting like rabbits and squirrels, varmint control, and target practice. It delivers significantly more power than .22 LR with a flatter trajectory and better range, making it effective for hunting out to around 130 yards in experienced hands. The heavier 50-grain bullet in this Federal load provides solid energy transfer for reliable kills.
Will Federal Game-Shok .22 WMR feed reliably in semi-auto firearms?
Yes. Federal designed the Game-Shok line with jacketed hollow point bullets specifically to ensure smooth feeding in semi-auto rifles and handguns. The brass cases and bullet construction work together to feed consistently, though you should always verify your firearm is rated for the ammunition you're using.
How does the 50-grain bullet compare to lighter .22 WMR loads?
The 50-grain load trades some velocity for bullet mass, giving you deeper penetration and more energy retention at distance compared to 30 or 40-grain options. It's a good middle-ground for hunters who want versatility without buying multiple loads. The slightly heavier bullet also tends to be less affected by wind at typical hunting ranges.
Is this ammo reloadable?
Yes. Federal Game-Shok uses standard brass cases and rimfire primers, making the fired cases suitable for reloading. Rimfire reloading requires different equipment and techniques than centerfire reloading, so make sure you have the proper dies and knowledge before attempting to reload these casings.
