Not interested in the suppresed qualities, just fact its affordable at standard velocity and unusual bullet weight that a old mil surp trainer seems to really like. Like to have different bullet weights around for the odd ball that may like it. Fast service and affordable price. 8 months ago ** ** ** ** ** ** GARY GREENVILLE, NC good price and fast shipping. not as quiet as cci sub-sonic 9 months ago ** ** ** ** ** ** Verified Customer Love this ammo. Performs as needed and quiet with the suppressor. 9 months ago ** ** ** ** ** ** Jennings Lolita, TX I got these to help with the problems that my neighbor has with my frequent shooting. Constantly called the sheriff to complain about the noise and God only knows what else. These subsonic rounds when shot with a Huxwurxs Flow 22 suppressor are really quiet. However, the neighbor can still hear the ting of the steel plates. Hey, I've done what I can and I'll exercise my legal right to shoot targets on my property. All kiddin' aside, these work well in my new S&W 22 pistol. I've used about 200 out of the first box with no failures to report. I'll get more when these are spent. I got a great price including a good shipping price. They shipped quickly and I'm well pleased with the purchase. 9 months ago ** ** ** ** ** ** William BUCKNER, MO Ammunition was shipped quickly and price was good. 10 months ago ** ** ** ** ** ## Shop 22 LR Firearms ```json {"@context":"https://schema.org","@graph":[{"@id":"https://www.kygunco.com/#website","@type":"WebSite","description":"Shop KYGUNCO for firearms, ammo, accessories, parts, and outdoor gear at low prices with fast, easy nationwide shipping.","name":"KYGUNCO","url":"https://www.kygunco.com/","publisher":{"@id":"https://www.kygunco.com/#/schema/organization/kygunco"}},{"@id":"https://www.kygunco.com/product/winchester-ammo-super-suppressed-22lr-45gr-350ct#webpage","@type":"WebPage","description":"Subsonic .22LR ammo built for suppressed firearms.
