The Winchester Wildcat Super Speed 22LR pushes a 40 grain copper-plated hollow point to 1300 feet per second, generating 150 foot-pounds of energy at the muzzle. Rimfire ammunition — a centerfire primer is struck by a firing pin at the base rim of the cartridge rather than a central primer pocket — is defined by its cost-effective design and reliable ignition in sporting rifles and handguns. Winchester manufactures this round in the United States with uniform powder charges, clean-burning propellant, and non-corrosive priming to sustain cycling performance across semi-automatic platforms. This load is purpose-built for the Winchester Wildcat rifle and similar semi-auto rimfire actions where reliable energy transfer and ejection timing matter.
Performance at a Glance
The copper-plated hollow point expands on impact against soft tissue, delivering terminal performance on small game — squirrels, rabbits, pest birds — while the plating reduces barrel fouling compared to exposed lead projectiles. At 1300 fps muzzle velocity, this load sits in the “high-velocity” segment of 22LR offerings, outpacing standard-velocity rounds (1070-1150 fps) and sitting below hyper-velocity variants (1400+ fps). Energy on target at 50 yards remains sufficient for ethical harvest of game within 75 yards, the practical effective range for most 22LR hunting applications.
