Winchester® developed M-22™ Rimfire Ammo specifically to function reliably in MSR (Modern Sporting Rifle) semi-auto, rimfire firearms with high capacity magazines. The 40-grain, black copper-plated, round-nose bullet shoots accurately, feeds reliably, and leaves minimum lead fouling in the barrel, feed ramp, and mag lip, making it an excellent choice for high volume shooting. Winchester uses clean-burning powder and priming in their M-22 ammo that also contributes to maintaining firearm actions clean for reliable function. Shooting Winchester M-22 Rimfire Ammo in AR-style semi-autos is a practical, cost effective method of tactical training, as well as a great way to have fun plinking and target shooting.

  • Designed specifically to function in MSRs
  • Black copper-plated, round-nose bullet
  • Minimum lead fouling
  • Clean-burning powder

Good choice for bulk ammo I used this ammo in my S&W 22a-1 over the weekend. The bullet sits firmly in the case; it is not loose or shaky. The rounds fed well and with only one failure to feed with over 100 rounds fired in less than an hour, this round performed very well (it's more likely my mag springs were too tight rather than a problem with the ammo). The accuracy is excellent and I have no complaints there. My one concern was that one round was malformed to the point where the bullet looked like a Hershey Kiss. Otherwise, for the price, you can't beat this ammo. September 25, 2012
Winchester 22 LR Bullets These Bullets are the Best of the Best Winchester Bullets you can buy on the Market. They shoot Awsomely, and give you tight groups when Shooting. I would recomend to any enthusiast or Average shooter. For the cost of these Bullets at $49.99 it's a great buy, you won't be dissappointed. TScion of San Diego. May 28, 2012
Great 22 rounds I have several 22 rifles and pistols. I have a AR clone (Colt/Umarex) and a new H&K MP5 clone, both function extremely well with this ammunition. I had previosly been limited to CCI Mini Mag but at around $8 per 100 it was kind of pricey. This is great ammo and functions just as well as the CCI but at a fraction of the cost. My 22 pistols, Sig Mosquito and Sig 1911-22 both worked better with this ammo than the CCI. Fewer FTF and FTE problems. If this is the case long term I will definitely stock up on another 2 boxes (1000 per). May 12, 2012
Winchester, M-22, .22 LR Ammo. This ammo, feeds great,and is very clean. Fired about 200 rounds, no failures to feed,one round failed to fire, accuracy is good. I have a Marlin Model 60 & a Winchester Model 190, both ammo sensitive, this ammo worked great in both. It is worth the higher price. May 4, 2012
