Winchester Super-X Subsonic HP Rimfire Ammo
Winchester® Super-X® Subsonic HP Rimfire Ammo is an ideal choice for small game hunting or pest control in areas where loud muzzle blasts attract unwanted attention, as well as for use with firearms equipped with suppressors. The 40-grain, truncated cone, hollow point lead bullet is designed specifically to expand reliably at subsonic velocities. Winchester Super-X rimfire ammunition is manufactured to exceedingly high standards with reliable priming, and uniform powder charges and bullet dimensions to yield consistent accuracy from one box to the next. Clean-burning powder and priming contribute to maintaining firearm actions clean for reliable function. The minimum muzzle blast from Super-X Subsonic HP Rimfire Ammo makes it a great training round for new shooters and great for hunting.

The brands tested were CCI Subsonic, Aguila Subsonic, Aguila sniper subsonic, dynamit nobel subsonic, and Remington Subsonic, and Winchester Super X subsonic.
The top performers were the Nobel and Win Super-X sub. Both were equally quiet and consistent with an extreme spread of 6.9feet per second over 20rounds, average velocity from my gun was 988fps (just right to avoid sonic crack), zero cycling issues. With my suppressor it is action noise only, but because of the large cavity in the hollow point you can actually hear the bullet flying. They are very accurate and with the MASSIVE hollow point and soft lead bullet they are devastating on small game"
