What customers like
Reliability & Function42%
Works great in my, soon to be regulated by the ATF, CMMG M4 300AAA BLACKOUT Brace attached SBR. No FTF, FTC, OR DUDS AFTER OVER 1000 ROUNDS FIRED.
Subsonic Performance23%
Using a bolt action with a .30 cal YHM can... UNBELIEVABLY QUIET, and consistent accuracy to 200 meters, with TIGHT groups... Almost "Hollywood" quiet.
Accuracy & Grouping23%
I tested four different brands to target shoot from 100 to 400 yards with a 16'' AR. This M855 consistently had the best groups.
Value & Affordability15%
Great bulk ammo that your wallet doesn't mind works great for target and training ammo, and even self defense if needed.
Hunting Effectiveness13%
I took 3 deer with this ammo this season and I really does the job.Going to try it out on some hogs after deer season.
Common concerns
Quality Control Issues25%
The lack of quality control is quite evident. Every bullet was seated at different heights, the tips of every bullet were also smashed, and the brass was heavily tarnished.
Failure to Feed/Fire21%
I purchased 120 rounds for a new build. And I have had nothing but failure to feed after failure to feed .
Defective Ammunition15%
I checked the other 3 boxes I purchased and found 7 more (six in one box). I will not purchase Winchester ammo again
Inconsistent Bullet Expansion6%
She placed a perfect 125 yard vitals shot on a first year small buck and we found the round did not expand hardly at all.
Frequently Asked Questions
Winchester 300 Blackout Ammo
Is Winchester 300 Blackout ammo good?
Winchester 300 Blackout is reliable and accurate. Subsonic loads cycle well through suppressors, and hunting rounds perform effectively on deer and hogs. Around $23 per box with 13 variants available. Performance varies by load, so match your selection to your intended use.
Is Winchester 200 grain 300 Blackout good?
Winchester 200 grain .300 Blackout is a solid subsonic load, well-suited for suppressed shooting and target practice. Users report consistent accuracy in carbines and pistols. It's not ideal for hunting. Pricing runs roughly $1–$2 per round depending on the variant and retailer.
What is the best grain bullet for a 300 Blackout?
No single "best" grain exists—it depends on your use. For hunting deer, 110–125 grain supersonic rounds deliver reliable expansion. For suppressed shooting, 220 grain subsonic loads cycle reliably and stay quiet.
What is the best subsonic ammo for 300 Blackout?
Best subsonic .300 Blackout options depend on your use. Black Hills 220gr OTM and Fiocchi 220gr HPBT MatchKing rank highly for accuracy. Sellier & Bellot 200gr FMJ offers reliable plinking. Prices typically range from $14.99 to $98.09 per box. Test different loads in your specific barrel for best results.
What is the best 300 Blackout subsonic hunting ammo?
Best subsonic hunting ammo depends on your rifle and target game. Discreet Ballistics 188gr Selous Machined Expander and Hornady 190gr Sub-X are popular expanding options. Expect to pay around $23 per box, with prices ranging $15–$98. Always test loads in your specific rifle before hunting season.
Is Winchester ammo good quality?
Winchester ammunition is reliable and consistent across most loadings. Budget lines sacrifice some accuracy, while specialized rounds like Defender and Ballistic Silvertip deliver higher performance. Law enforcement and hunters widely trust the brand.
What is the effective range of 300 Blackout for deer?
Effective range for deer is generally 100–200 yards with supersonic loads. Most hunters limit shots to 150 yards for reliable terminal performance. Subsonic loads are effective out to 200 yards with proper bullet selection. Bullet choice matters significantly, with 110–125 grain supersonic rounds offering the best balance of velocity and energy at distance.
Can you coyote hunt with a 300 Blackout?
Yes, 300 Blackout works for coyote hunting. Supersonic loads with 110–125gr bullets are effective at ranges under 200 yards. Many hunters prefer .223 or .204 Ruger for flatter trajectories at longer distances. Avoid subsonic loads, as they lack sufficient energy for clean kills.
Can you shoot super suppressed 300 Blackout ammo without a suppressor?
Yes, you can shoot subsonic 300 Blackout without a suppressor, but it will still be loud and hearing-unsafe. Subsonic ammo is designed to eliminate the supersonic crack, but the muzzle blast remains. A suppressor is needed to bring it to hearing-safe levels.
What is the quietest .300 Blackout round?
Quietest performance depends on suppressor and testing conditions, but Hornady Subsonic 190gr Sub-X consistently ranks among the quietest options. The Underwood Subsonic 220gr HPBT ranked 5th in testing. A suppressor further reduces noise, but subsonic .300 Blackout rounds can reach hearing-safe levels without one.
