190 Grain 300 Blackout Ammo Guide

Fenix loads a 190 grain Hornady Sub X projectile in this FXP Subsonic product. Hornady describes the Sub X rifle design with a lead core, grooves in a gilding metal jacket, a flat profile, and a Flex Tip insert in the hollow point cavity. Those construction details provide a useful distinction from the 220 grain FMJ option without assigning an unsupported outcome. Both Fenix products come in 100 round packs. Compare projectile type and product category first, then view the 190 grain product details for current price and availability.

A product led subsonic selection

Fenix explicitly labels the 190 grain FXP load subsonic and publishes 1,000 FPS. The product page states that it was tested in several rifles with barrels from 8 to 10.5 inches, with and without suppressors. Fenix also notes that rifle setups vary and that gas settings or buffer weights may need adjustment. Keep that configuration note with the product rather than assuming identical function across rifles. For a heavier FMJ training choice, compare the 220 grain product in the same subsonic collection. View the 190 grain product page for complete details before ordering.
