Description
There's a reason the .22 WMR has stuck around as the go-to step-up from standard .22 LR, and this Remington Magnum Rimfire load shows exactly why. The 40 grain Pointed Soft Point bullet leaves the muzzle at 1910 fps and carries 324 ft lbs of energy, giving you a flatter trajectory and more authority on impact than you'll get from rimfire's little brother. This case packs 2000 rounds split across 40 boxes of 50, so if you're running traps for ground squirrels, keeping a varmint rifle fed all season, or just tired of restocking every few weeks, this is the way to buy it.
What Makes This Remington Magnum Rimfire Load Worth Stocking Up On
Remington built this line around consistency from case to case, tightening up manufacturing tolerances and dialing in primer mixes so you get uniform ignition and pressure shot after shot. That translates to fewer flyers and a load that groups the way you expect it to, whether you're shooting off a bench or tracking a coyote through brush. The pointed soft point design is built for controlled expansion, opening up on impact while still holding together enough to punch through where a standard hollow point might not.
Where This .22 WMR Load Earns Its Keep
This round works equally well out of a bolt gun, semi-auto rimfire rifle, or a magnum-chambered revolver, so it covers a lot of ground for one cartridge. Prairie dogs, crows, tree squirrels, and coyotes at closer range are all fair game with the extra velocity and energy the .22 WMR brings over standard .22 LR. It's also a solid choice for anyone running a rimfire trainer for centerfire varmint or predator hunting, since the trajectory and recoil management carry over reasonably well.
Buying the Remington Magnum Rimfire Case Instead of Single Boxes
Buying by the case just makes sense if you shoot this caliber with any regularity. You're not hunting for ammo every other week, you're not paying shipping multiple times, and you've got enough on hand to run through a full hunting season or a summer of range trips without a second thought. Brass cased, boxer primed, and built on Remington's standard rimfire manufacturing line, this is the same load a lot of small game and predator hunters have leaned on for years.

Frequently Asked Questions
What's the difference between this Remington Magnum Rimfire load and the Premier Magnum Rimfire line?
The standard Magnum Rimfire load uses a Pointed Soft Point bullet built for penetration, while the Premier line uses a polymer tipped AccuTip-V bullet designed for more explosive expansion. Both run at similar velocities, but the PSP tends to hold together a bit better on tougher game while still opening up on impact.
Can I shoot this .22 WMR ammo through a revolver or just rifles?
This load works fine in both magnum chambered revolvers and rifles, since .22 WMR is a rimfire cartridge chambered in a variety of firearm types. Just double check your specific firearm is rated for .22 WMR before loading up, since it runs at higher pressure than standard .22 LR.
Is buying the 2000 round case actually a better deal than individual boxes?
Buying in bulk almost always saves you money per round compared to grabbing single 50 round boxes, plus you're not paying multiple shipping charges over time. It's a solid option if you shoot this caliber regularly or want enough on hand for a full hunting season.
What kind of game is the 40 grain PSP load suited for?
This load is a popular pick for prairie dogs, ground squirrels, crows, and similar small game where you want more reach and energy than standard .22 LR provides. Some folks also use it on coyotes at closer distances, though a lot of predator hunters prefer to pair it with a centerfire round for longer range work.
