Sellier & Bellot 300 AAC Blackout 200gr FMJ Sub-Sonic Ammunition 20rds – SB300BLKSUBA

Good ammo for the price. Clean , accurate, and reliable. I use them for my plinking and target ammo.

I ran several boxes of this ammo though a Palmetto State Armory AR-15, using a 16" barrel with a pistol length gas system. The rifle is not suppressed. This ammo ran 100% perfectly, zero problems cycling the action, no failures to feed, no failures to extract or eject. Tight groupings down range. I will buy more of this ammo without hesitation. GrabAGun has a great price on this ammo. Buy it.

I’ve had no issues maintaining POA/POI with these rounds. I can’t speak for grouping as I am only concerned with reasonable grouping not single hole punching. They will hold hold +/- MOA, so its more than good enough for me personally. Haven’t come across any travelers in the last 100 rounds.

It's hard to find ammo for a .300 blackout for decent prices these days , but S&B offers some of the best on the market for an inexpensive ammo that is both accurate and great for having fun. No it is not Black Hills sub moaammo , but it does the job at half the price. Thank You S&B !!!! And GAG !

Excellent in concept and execution. The 220 grain subsonic ammo doesn't stabilize well in most guns and tends to chew up suppressor baffles. This 200gr. projectile stabilizes more efficiently in a 1:8 barrel twist.

This is a fun and awesome to shoot out of my 300 blackout Ruger American with suppressor. Very clean and accurate! Very low noise signature!

velocity a bit slow but works great for the price....which is great! About 80 fps slower than 220g american eagle in my 5.5" sig Rattler.

Im happy with it. Some of the packages came crushed but the ammo was in great shape. Shipping was fast and i will buy more when its back in stock. Thank you!

GREAT PRICE I BOUGHT 5 BOXES OF THESE. THE SHOOT JUST FINE IN MY AMERICAN TACTICAL IMPORT 300 AAC BLACKOUT THAT I ALSO BOUGHT AT GRAB A GUN. I LOVE THEIR PRICES AND THEIT PRODUCT IS A 5 STAR RATING IN MY BOOK. IALWAYS GET GREAT FAST SERVCE AND THE SPIPPING IS ALSO FAST. PROFESSIONAL SALES REPS THAT ARE KNOWLEDGEABLE OR THE FIREARES THEY ARE SELLING.

These rounds are awesome. I am shooting a 10” Heavy barrel and they are spot on at one hundred yards.

Seems like the rounds vary in load. Had problems with the length of the round being shorter than what I have used before. and lots of jambs including a round stove pipe leaving only the bottom of the shell. Will never use again.

Used this ammo in my .300 Blackout with a can on and it was extremely quiet. Took it out in my backyard with several friends around and fired a few rounds and they remarked how quiet it sounded. Recommend this for a suppressed .300 AAC Blackout

I have run several of these thru my 10.5 inch blackout with zero issues and great success. I will be buying more.

Would highly recommend this ammo. It shoots consistently and accurately. For the price, this is great range day ammo.

I’ve run several hundred of these 200gr bullets through my Springfield Saint 10.5” pistol, suppressed with silencerco hybrid 46 and omega 300. Zero failures so far. I’ve even run 60ish rounds while using binary trigger and the ammo cycles really well.

I haven't had a chance to shot these yet. If problems arise, I'll be sure to include in this review.

Tried subsonic and supersonic as well, both worked great and had no malfunctions. For the money it's hard to beat.

Worked well in a 300 AAC pistol. No FTF or FTE in 20 rounds through a new build. They are a bit pricey at $1 = 1rd, but I will buy more when I get the chance.

Bang, bang, bang. Wait for it.... Splash, splash, splash. Good slow moving heavy projectile ammo that hits hard and has cycled flawlessly in my PSA AR pistol.

Great round. My only complaint is I didn’t buy more. This ammo sold out quick. Shot the same brand super sonic and this subsonic round and wow what a difference.
