Comments and Reviews on Hornady Subsonic 300 AAC Blackout Ammo 190 Grain Sub-X - 80877
Clean, accurate and non jamming ammo for my suppressed Sig Sauer MCX Rattler.
Comments and Reviews on Hornady Subsonic 300 AAC Blackout Ammo 190 Grain Sub-X - 80877
Great Hornady Subsonic ammo for supressed hunting very accurate!
Comments and Reviews on Hornady Subsonic 300 AAC Blackout Ammo 190 Grain Sub-X - 80877
These are ok. Just ok. The expansion isn’t big. The accuracy is ok, but I got better with other subsonic ammo. In my opinion, in my guns, this ammo is a poor performer at a premium price. 16” nitride bbl got ~3 MOA 8.5” phosphate bbl got ~5 MOA 16” stainless bbl got ~2 MOA
Comments and Reviews on Hornady Subsonic 300 AAC Blackout Ammo 190 Grain Sub-X - 80877
It put down a deer last year at 75 yards though my suppressed gun. I was excited to recover the round to see how the expansion performed but I quickly found out it had gone completely through the deer. But the deer didn't run so it must have done it's job.
Comments and Reviews on Hornady Subsonic 300 AAC Blackout Ammo 190 Grain Sub-X - 80877
Haven't really tested the expansion capabilities yet but it shoots great as a companion to the Black 208gr I practice with.

Price was average for the product. A membership with target ammo would make it much better. The shipping was excellent especially for the time of year it was and it was packaged very well.
