Sub 300 Blkout
Run my 300 subsonic only, full time Q Thunder Chicken. Have my adjustable gas block set up perfect for these 220gr subs. They run consistently I’ve tried other subsonic and failure to cycle is the issue usually. This is the second purchase of bulk. I usually train twice a week, these always perform.

300 BLCKOUT 220GR TMJ SUBSONIC
100% recommend!! If only I could share pics. Price was skeptical low, did not make up for with shipping. Arrived quickly and packaged perfectly, no busted boxes "leaking" loose rounds into the main box. Range day; flawless execution. Running subsonic thru suppress 7.5" with the holes where I say at 100 yards. These guys are legit and getting Christmas card from me. Finally. Thank you, Minuteman Munitions.

Great Choice for 300 BLK
First time buyer here and I purchased 120 rounds to test in my firearm as it tends to be very picky with ammo. All 120 rounds worked perfectly, not a single issue or malfunction and I even trend to to cause a malfunction. 100% will be purchasing again. Great choice for range ammo.

pew pew pew
Ever since buying some 9mm on a whim a few years back, I've been really impressed with MinutemanMunitions - I always check their stock now before buying anywhere else. I love their products and I'm really impressed with these 300 blk subsonic rounds. I always consider "Fun per dollar" value and this definitely hits the mark. Please don't buy these up before I have a chance to purchase more :)

300 blk out 220 g subsonic
Between my local shop where I first found this ammo and here on the online site I have accumulated a thousand rds so far. This by far is the best 300 blk out subsonic ammo. It’s quite out of my 5 inch maxim pdx and I haven’t had one failure yet. I recommend this ammo to anyone especially with sbr and suppressors. Hopefully the price stays the same because I am trying to stock pile as much as possible. I promise you won’t regret getting as much as possible.

.300 BLK - 220gr
Extremely consistent, very quiet and most importantly, accurate. This is my favorite 300 BLK ammo. Its ridiculously quiet through my SureFire SOCOM 300 and always accurate. Look no further!!

crappy ammo that dont cycle
I bought 360 rounds of this ammo, and it will not cycle with a suppressor. its pretty much worthless. i guess ill have to take them apart and load them properly. UPDATE I SINCERELY Apologize for the negative review I recently gave your ammo. I'm an old grumpy sniper, who at times jumps to conclusions to which I'm at no fault. since my review I have found the fault of the failure to cycle issue was in fact my rifle. I hereby strike my original review and give it four stars for price and packaging( love the 30 rnd boxes). I do find the accuracy to be less than optimal, but suffice for what it is intended for. Again, I apologize for the bad review.

.300 Blackout 220 grain
This ammo is impressive. I've purchased several times now and have not had a bad round - very consistent. I like that Minuteman uses shorter barrels to test velocity. And I haven't found any other retailer that compares to Minuteman's price per round along with their flat rate shipping. I will be back for more !
