Description
Federal Champion .22 WMR ammunition strikes the balance between power and practicality that makes this cartridge worth reaching for at the range. The 40-grain full metal jacket bullet delivers 1880 fps velocity with 314 ft-lbs of energy, giving you genuine magnum-class performance without the premium price tag you'd pay for specialized hunting loads. This is purpose-built training and target ammunition, meaning Federal dialed in what matters for range work: consistent velocity, clean-burning powders, and reliable feeding across different rifles and revolvers.
What Makes This Federal Champion Load Effective
The full metal jacket design spans the entire bullet from nose to base, preventing expansion and keeping performance predictable downrange. You get premium Federal brass with a rimfire primer system that's engineered for dependable ignition, shot after shot. This isn't a budget corner-cut either – the brass is reloadable quality, and the non-corrosive priming means your barrel stays cleaner during extended sessions. The powder burn is clean enough that you won't be spending extra time cleaning carbon fouling out of your action.
Why Competitors Choose Federal Champion for .22 WMR
The .22 WMR sits in a unique spot. It's got legitimate range and power compared to standard .22 LR, but loads like this Federal round make it practical for regular range time instead of just varmint hunting. The 1880 fps velocity keeps shots supersonic and reliable, and the ballistic coefficient of .111 means your point of aim stays reasonably consistent across different distances. Each 50-round box lets you work on accuracy and consistency without committing to expensive specialty ammunition or burning through centerfire ammo.

Frequently Asked Questions
What's the difference between this Federal Champion .22 WMR and other target loads?
This Champion line is designed specifically for range use, training, and practice – not specialized hunting. Federal built it with clean-burning powders and reliable primers to give consistent shot-to-shot performance. The full metal jacket construction keeps the bullet from expanding, which is what you want for target work where you're focused on pure accuracy rather than terminal performance.
Can I use Federal Champion .22 WMR in revolvers and rifles?
Yes. This ammunition works in any firearm properly chambered in .22 WMR, whether it's a rifle or revolver. Just make sure your gun is actually chambered for .22 WMR and not a different caliber like .22 LR, since mixing those up causes problems.
Is the brass reloadable?
The brass casings are quality Federal manufacture and can be reloaded, so if you're into hand-loading, you're getting usable brass. Since these are rimfire rounds, you'll need rimfire-specific reloading equipment, but plenty of people reload their .22 WMR cases regularly.
How does Federal Champion .22 WMR compare to other brands for target shooting?
Federal Champion competes well on consistency and value. The 1880 fps velocity and quality control keep groups tight at reasonable range distances, and you're not paying specialty hunting ammunition prices for training rounds. If you're just trying to put accurate shots downrange without breaking the bank, this is solid ammunition.
