300 Blackout Ammo Review

By / January 29, 2023

The 300 AAC BLK may not be able to replace the 5.56 NATO as your primary intermediate rifle cartridge, but that doesn’t mean it’s not an excellent round. In fact, there are plenty of applications where this cartridge performs incredibly. In this 300 Blackout ammo review, we’ll list those applications plus more reasons why you should add this round to your ammo inventory.

300 Blackout Ammo Review

The 300 BLK is a favorite hunting and self-defense round among gun enthusiasts because of its versatility. You can fire it suppressed or unsuppressed. You can also produce subsonic and supersonic loads with it. Most importantly, it’s more powerful than the 9mm cartridge and it performs excellently with the AR-15. 

The 300 Blackout is most potent when fired through suppressor-equipped short barrels or when using subsonic ammo. After all, it was designed for it.

Great price on 300 Blackout FMJ Ammo. I took it to the range several times and after shooting hundreds of rounds – zero issues/malfunctions. It is hard to beat it at this price, I will be buying more!

What Customers Say

Shot these out of a stock Daniel Defense AR with a 16in barrel and a silencerco suppressor. The bolt cycling and the round hitting the target at 100yds was louder then the actual shot. Gun cycled perfectly and I had zeros issues. Can’t wait to go to the range again. Great round for the money.

I was researching for a practice round that had the same point of impact as my “working” round. Which is the Hornady Sub X 190gr. I use an 8 1/2 in. Suppressed SBR. I found exactly what I was looking for with this S&B 200gr subsonic. Same point of impact, same great accuracy, at almost half the cost.

This order was to restock my supply of 300AAC hunting ammo. It is accurate and terminal ballistics are good. Grandson has one shot kills on deer out to 150 yards. I’ve only shot the ammo at 100 yard targets but wasn’t disappointed in any way.

Mobuck

I use this ammo for hunting, hard hitting round at 100 yds +. Not had any misfires or jams.
