The Winchester Super 22LR 45gr 000 case brings 2,000 rounds of purpose built suppressed ammunition to shooters who want quiet shooting in serious quantity. Each cartridge carries a 45 grain black copper plated hollow point at 1065 fps, which is deliberately kept below the speed of sound. Subsonic velocity is what makes a suppressor actually work.
A suppressor cannot silence a sonic crack. If the bullet breaks the sound barrier you hear a sharp report regardless of how good the can is, which is why dedicated subsonic ammunition exists. Match the ammunition to the suppressor and the difference is dramatic.
Why the Winchester Super 22LR 45gr 000 case is different
The 45 grain bullet weight is the key. Heavier than the 40 grain standard, it delivers useful energy while staying comfortably subsonic, so you get quiet shooting without the load feeling anemic. The black copper plating reduces fouling and helps the cartridge feed smoothly.
Suppressor owners, varmint hunters working near livestock, and anyone shooting where noise is a genuine consideration are the natural buyers for a Winchester Super 22LR 45gr 000 case. Two thousand rounds is a supply that supports real volume shooting rather than occasional novelty. Suppressed rimfire is addictive once you try it.

Specifications and what subsonic really means
Caliber is .22 Long Rifle, bullet weight is 45 grains, bullet type is a black copper plated hollow point, muzzle velocity is 1065 fps and the case holds 2,000 rounds. The load is designed specifically for suppressed firearms. Everything about it targets a reduced noise signature.
Reduced noise is the entire promise of the Winchester Super 22LR 45gr 000 load, and it is delivered through velocity rather than marketing. Staying below roughly 1125 fps keeps the bullet subsonic in most conditions, which eliminates the crack and leaves only the muted action noise. The result genuinely surprises people the first time they hear it.
Suppressor use, cleaning and storage
Expect to clean more often when shooting suppressed rimfire, because a suppressor collects lead, carbon and unburned powder quickly. That is normal and it is the price of the quiet. Plated bullets help, but nothing eliminates the maintenance entirely.
Cycling can be an issue in some semi automatic rifles, since subsonic ammunition produces less impulse than a high velocity load. Run a magazine or two of the Winchester Super 22LR 45gr 000 rounds through your rifle to confirm reliable function before you commit to a long session. Bolt actions never care at all.
Store the case somewhere cool and dry and it will remain reliable for many years, since rimfire priming ages very slowly in good conditions. Decant a few hundred rounds into an ammo can for range use and leave the rest sealed. Humidity is the only real threat.
Buy deep while it is available and look through the rest of our ammunition catalog for anything else on your list. Purpose built subsonic ammunition is among the first things to sell out.
Quiet shooting changes how often you shoot and where you can do it, and a Winchester Super 22LR 45gr 000 case is what keeps that going. Fill the shelf once and enjoy the silence. This ammunition ships straight to your door wherever state and local law allows.
