HORNADY 190-GRAIN SUB-X $1.15 / ROUND
Announced in December 2017 and released for sale three months later, Hornady added an expanding subsonic bullet to its existing five Blackout offerings.
Built to their usual standards, the bullet features a red polymer tip to initiate expansion, a detail no doubt familiar to users of their Critical Duty line of pistol ammo. In our test rifle, it proved to be an accurate and consistent performer, and if a lone flyer were discounted, would’ve turned in a 0.36-inch group. Of the conventional jacket-and-core projectiles in this test, it was the only one not to separate. Note, however, that some polymer mags may have problems in presenting the blunt tip high enough to make it up the feed ramp in your favorite semi auto. Either use regular old GI versions or Magpul’s 300 BLKspecific offering.
