Description
Winchester Super-X .22 WMR 40 Grain Hollow Point
This is the classic .22 Magnum load that's been doing the job for decades. The 40-grain jacketed hollow point gets pushed to 1910 feet per second with 324 foot-pounds of energy, which puts it right in the sweet spot for varmint work and small game hunting. It's a flat-shooting cartridge in this grain weight that won't blow up edible game at practical hunting distances when you place your shots well.
What makes Winchester Super-X a reliable choice
Winchester's Super-X line has a solid reputation for consistent ignition and dependable feeding. The brass casing and non-corrosive primer mean you get reliable performance shot after shot, and the ammunition cycles smoothly through most .22 WMR rifles and revolvers without drama. This is the kind of load that rifle owners have standardized on for a reason.
Versatile performance for real hunting situations
The 40-grain JHP is versatile enough to handle multiple applications. From prairie dogs and ground squirrels out to roughly 100 yards, to rabbits and brush hunting, this bullet weight offers controlled expansion without excessive fragmentation on smaller game. It's effective enough to handle larger varmints like coyotes when you get solid hits, and the trajectory is forgiving enough for practical field shooting. Fifty rounds per box gives you plenty to work with for a day of hunting or serious range time.
Built to Winchester's standards
Each round features a lead core with a copper jacket, proven construction that delivers consistent ballistics. The ammunition is new production and non-corrosive, making it suitable for any .22 WMR firearm you own, whether that's a bolt-action rifle, lever gun, pump, or magnum revolver.

Frequently Asked Questions
What's the effective range for Winchester Super-X .22 WMR with a 40-grain bullet?
The 40-grain loading is most effective for small game and varmints out to roughly 125 yards when you're making accurate shots from a rifle. At this range, the round still carries enough velocity and energy to deliver reliable terminal performance. Past 125 yards you'll need to account for significant bullet drop and energy loss.
Can I use this ammunition in both rifles and handguns?
Yes. Winchester Super-X .22 WMR works in both rifle and handgun platforms chambered for .22 Magnum. Keep in mind that handgun barrels will produce noticeably lower velocities than rifle barrels due to reduced powder burn time, but the rounds will still function reliably and perform well for their intended purposes.
Is this ammo suitable for hunting edible game?
The 40-grain hollow point can work for small game like rabbits and squirrels, but placement is critical. Aim for head shots on edible game to minimize meat damage and ensure ethical kills. The hollow point is designed primarily for controlled expansion on varmints like prairie dogs and predators where meat preservation isn't a concern.
Why would I choose 40-grain over lighter 30-grain .22 WMR loads?
The 40-grain offers more energy transfer and penetration than 30-grain loads, making it better suited for larger varmints and medium-range hunting. You trade some velocity and trajectory flatness for increased stopping power and deeper penetration, which many hunters prefer for versatility across different game sizes.
