As a subsonic, it performs poorly from the AR15 in extreme cold (doesn't work). I look at it more as a novelty than anything else, to be honest. It's only relevance as a fair weather friend is as a subsonic toy, unless you limit your hunting or door-kicking to warm weather where pistol powders will actually cycle the action, and as a super, it is easily outdone by many other cartridges.

In my opinion, it is the product of a very massive marketing scheme more than any inherent performance.

If you are limiting yourself to these two choices, there is no real comparison with 6.8 SPC.

However, for you that are vested in it, be aware that there are people you haven't heard of that actually do testing in conditions that you probably never will leave the front door into, especially in NC.

You wouldn't be aware of the extensive testing done by coalition partners with 300 Whisper well before Freedom Group jumped on this. You wouldn't be aware of the testing done by manufacturers who you don't even know that make 300 BLK AR15's, as well as ammunition. You are basically in the dark about some of the most important RDT&E of the 300 Whisper, and will continue to remain so.

There are coalition partners who deal with extreme cold weather that you rarely see in the US, unless you're in the Great Lakes region or Alaska. Reliability is important to them in extreme cold. 300 Whisper subsonic SBR does not work in those conditions. Sorry you did not get the memo, but it doesn't matter to you anyway. You'll never see those temps, unless a strange polar vortex works its way down through North kakalakki. Looks like you don't have anything to worry about.



For those that are in Montana, Wyoming, and parts of Colorado that have 300 Whisper/AAC/BLK AR15's, with 8" to 10" barrels, with a suppressor, and any of the subsonic loads: Please go outside, to the range, whatever, and see how your gun runs. Right now, all the worst temps in the US are roughly 16-20 degrees higher than the temps I'm talking about, like -30 C / -22F.

As you can see, we're nowhere near those temps, even with the Polar Vortex. I do know that brass-cased 5.56 and 7.62x39 work fine at those temps, including shooting in high volume, with a lot of heat/freeze/heat/freeze cycles on the guns over days.

You also exposed yourself as someone who can't let an emotional connection with this cartridge keep you from characterizing my understanding of the AR15 gas as "rudimentary". To the contrary, I'm pretty sure you have a lot to learn about the AR15 gas system, and as you so correctly pointed out in the beginning of your emotional rebuttal, the party is way ahead of you, and no, you did not get an invitation to the extreme cold weather testing on this cartridge.

As to the marketing by Freedom Group, I've personally experienced it from FG executives at SHOT F2F who don't know jack squat about guns, but saw an opportunity to jump in the market as venture capitalists. 300AAC is a money-maker to them, nothing more. They could care less about ballistics, as long as it sells well based on a comprehensive marketing scheme that millions of neckbeards will swallow for the mere fact that it is a .30 bore, and the addition of a 3rd decimal place implies some type of superior stacking against other calibers. As a sub, it's a functional system that does bring real capabilities to people who need them, as long as the weather is good.

Why wont people stop talking about this useless concept of a round.  It would finally go into obscurity and be gone if people would simply stop talking about it.

it is useless and horrible. and serves no purpose whatsoever for any possible use.

AAC is stuck with all those handi rifles that nobody wants and finally lowered the price to sell them so they can then try to say people have bought into this useless concept.

I wonder how much Freedom group paid PSA to sell those useless rifles.

good luck finding ammo, since nobody is making it, and it is one of the hardest cartridges to reload for.

that's your argument to tell me that 300blk doesn't work in a break action single shot rifle  

4198 is a rifle powder, another common powder used to improve ar cycling with subs.  but hey, you read it on the interwebz right?  I'll try and not use it when it's -22 degrees here in FL....    

i'd be curious as to what subsonic round you would recommend?

i'm not discounting his argument.   He clearly states MOST people won't ever be into the conditions that give the round problems in the US unless you live in the extreme cold.  So why are you cherry picking his examples to discount the effectiveness of a small, lightweight, simple and quiet rifle?

For a couple hundred bucks more I will get a ruger american ranch instead.
