Frequently Asked Questions
Hornady 300 Blackout Ammo for Sale
Is Hornady Black 300 Blackout subsonic?
Hornady Black offers both subsonic and supersonic 300 Blackout loads. The 190 grain Sub-X is subsonic, designed for suppressed shooting. The 208 grain A-MAX runs supersonic. Check the specific load when ordering, as Hornady Black includes multiple variants.
What grain is best for 300 BLK subsonic?
Subsonic 300 BLK performs best with 190-220 grain bullets, keeping velocity below 1,125 fps. The 220 grain is most common. Hornady's 190 grain Sub-X and Sellier & Bellot's 200 grain FMJ are reliable options. Heavier bullets retain energy better; lighter ones may fail to cycle some rifles.
Is 125 grain 300 Blackout good?
125 grain 300 Blackout is a solid supersonic load for target shooting, varmint hunting, deer, hogs, and 3-gun competitions. Loads like the Hornady 125 gr SST and Nosler 125 gr Ballistic Tip are proven effective for deer and hog hunting at short range. Expect to pay around $30 per box.
Is Hornady Black 300 Blackout good for deer hunting?
Hornady Black 300 Blackout works for deer hunting if you keep ranges under 100 yards and choose the right load. The 125gr SST is a proven deer load with reliable expansion. Some heavier subsonic solids like the 200gr Maker REX also expand reliably. Typically around $30 per box.
What is the effective range of a 300 Blackout for deer hunting?
Most hunters keep 300 Blackout deer shots within 200 yards, though supersonic loads like 125gr bullets can perform well out to 300 yards. Heavier subsonic loads drop more steeply but can be effective beyond 200 yards with precise shot placement. Barrel length, ammunition, and shooter skill all affect practical range.
Is 300 BLK good for coyotes?
Yes, 300 Blackout works for coyotes using supersonic loads, typically 110–125 grain expanding bullets. It's most effective within 150 yards. Hunters wanting longer range often prefer .223 or .204 Ruger, but for close-range work or suppressed setups, 300 Blackout is a solid choice.
