Atomic Ammunition’s Subsonic Rifle Ammunition

I'm on the fence with this one. Out of the 50rds. 8 of them seem to go hypersonic.Definately a "noticeable crack. That and the price made me give it 4 stars. On the plus side they are bright shiny new brass,group less than 1" @ 50yds. not even really trying hard, and the plastic box they come in can be reused for reloads. These WILL NOT cycle AR actions,at least not mine. Maybe if you had adjustable gas block,but I'm not getting in to that yet.

I had just received my order and could hardly wait to put some rounds down range. I found it had very light recoil compared to what I normally shoot. Very quiet also. It cycles like a champ. Quite accurate as well. Looks clean and pretty in the box. I'm keeping that red box to hold my reloads. A great value all the way around. I'll be back for more!

This is a review of second box. I bought both boxes at same time they both have same production date stamped on bottom. 4 of the 50 went hypersonic with the noticeable crack. 3 of the rds.( WHILE loading into mag) the projectile went down into the casing.This was while I was loading the mag with a LULA loader. Had another 4 give a odd sounding report when fired. Not hypersonic crack I was figuring maybe the projectiles slid back while feeding.Like I said in my first review they do not cycle my AR so I cycle 1 by 1. It seemed to have that mil sec of delay,but that's my guess. I'm glad I didn't by more than I did. If you think about it @ 1050fps your .223 is now a .22lr You are better off getting subsonic 22lr there way cheaper. Only difference is AR is cooler looking than a 22. My apologizes to anyone who used my first review as a guide to purchasing these bullets. Maybe it was a bad batch but that's what I bought and all I have to judge by.

I've tried other subsonic ammo and they have not been as reliable or accurate as this ammo. Yes, you're going to get some variances, but not like others I've tried. My Remington 700 eats this stuff up and hogs don't like it. Even brought down a deer this year with it. Highly recommend this ammo if you're shooting suppressed.

Sounds like a .22 LR. Used in unsuppressed ruger American ranch 5.56. Moa groups. Point of impact was about 7 inches lower than super sonics, but very consistent which makes holdover adjustments easy. Didn't run into any hot rounds as mentioned in other reviews, but didn't run the entire box yet...

Quiet and accurate from Tikka T3 CTR (20" barrel, 1/11" twist) through Harvester 30. Consistent load groups under 1 MOA. I'd use this ammo next time I'm out night time varmint hunting.

Very quiet, and nice ammo particularly if you want to shoot suppressed. Velocity seems consistent, with a standard deviation of around 12 feet/sec with my setup. Drop at 250yards is roughly equivalent to standard match grade ammo at 1000yards.

Tried a box and I am definitely getting the sonic crack shooting it from by 16.5" barrel AR. I must have gotten an overpowered batch. Very disappointed.

After figuring out the hold over at 100 yards, we shot a 5 shot group with a Stock RPR .308 hosting a Silencerco Specwar and had a 0.75" Group at 100 yards. Bullet drop was about 15.5" but no hearing protection required and sounded like a suppressed 22LR.

Reliable, ultra quiet ammo. It does sound like a .22 LR round when not suppressed. When suppressed, this round is quieter than the action of the gun. Cost is the only negative.

I bought a box of these rounds and figured why not give them a try. Well they are everything that the one star ratings say. Wont cycle and they are pretty loud. I am running them through a 16" barrel with suppressor and they sound like my .22 un-suppressed. I use a conversion bolt in my AR for .22LR with the suppressor and use CCI 45gr 970fps suppressor rounds and they are silent. the only thing you hear is your trigger reset. Enjoy

Bought a box of these by mistake it barely had enough power I am surprised it even left the barrel and it wouldn't cycle the round. For a 77 grain bullet, that is 27 grains more than the average, you would expect more, The accuracy well there wasn't any that is what you get when the round is lobbed down range. Don't waste your time or money.

Very quiet and hard hitting rounds. If you are using this in a MSR platform it will need to be tuned to cycle the bolt carrier group. However without tuning if one quiet shot is what you need then this is the bees knees.

Shot well through my AR, they didn’t sound that loud either. Only thing was that there was one casing in the box without a bullet.
