Description
The .22 WMR has earned its reputation as the rimfire round that hits harder and reaches farther than a standard .22 LR, and this Remington loading is a solid example of why. Loaded with a 40 grain jacketed hollow point bullet, this ammo leaves the muzzle at 1910 fps and carries 324 ft lbs of energy right out of the barrel, numbers that hold up well even out past 100 yards. Brass cased and non-corrosive, it is built to feed reliably in both rifles and revolvers chambered for the round.
What Makes This Remington Magnum Rimfire Load Worth Stocking Up On
The jacketed hollow point design is meant to open up fast on impact, which makes this a practical pick for anyone dealing with squirrels, rabbits, prairie dogs, or other small game where quick, humane results matter. At 50 yards the load is still carrying around 230 ft lbs of energy, and even at 100 yards it holds onto roughly 162 ft lbs, so accuracy and knockdown power do not fall off a cliff once you stretch out the distance. The flatter trajectory compared to .22 LR also makes it a little more forgiving if your range estimation is slightly off.
Why the 2000 Round Case Makes Sense
This case breaks down into 40 individual boxes of 50 rounds, which is a setup that works well for anyone who burns through rimfire ammo regularly, whether that is a property with a serious varmint problem, a hunting camp that goes through boxes fast, or a shooter who just likes having a deep supply on hand instead of restocking every trip to the store. Buying it packaged this way also means you are not left scrambling mid-season when the smaller boxes run low.
A Dependable Choice for Rifles and Handguns Alike
This .22 WMR load works equally well out of a bolt action rifle, a lever gun, or one of the magnum rimfire revolvers and pistols built around this cartridge. Remington has been producing rimfire ammunition for generations, and this Magnum Rimfire line reflects that experience with consistent brass, reliable primers, and a load that performs the same way shot after shot.

Frequently Asked Questions
How does this Remington .22 WMR 40gr JHP load compare to .22 LR?
The .22 WMR case is larger and holds more powder than a .22 LR, which translates into noticeably higher velocity and energy at the muzzle and downrange. This particular load is moving at 1910 fps with 324 ft lbs of energy, giving it a flatter trajectory and more authority on small game than a standard .22 LR round.
What is this ammo best used for?
This 40 grain JHP loading is a solid choice for small game and varmint hunting thanks to its expanding hollow point design, and it also works fine for target practice and plinking. It is not really built for competitive precision shooting, but for general purpose rimfire use it covers a lot of ground.
Can I run this Remington Magnum Rimfire ammo through a pistol as well as a rifle?
Yes, .22 WMR is chambered in both rifles and handguns, and this load is built to function reliably across either platform. Just keep in mind that muzzle velocity will drop somewhat out of a shorter pistol barrel compared to the advertised rifle numbers.
Does the 2000 round case come as one bulk container or individual boxes?
This case is made up of 40 separate boxes of 50 rounds each, all packed together for a total of 2000 rounds. That makes it easy to grab a box at a time for the range or a hunt instead of digging through loose ammo.
