Why is everyone ditching the 300 BO

I think the AR pistols have run their course and we're starting to see more of them oh, and one of the calipers has to be the leader and typically it's the one that is expensive to shoot, or the one you were going to put a can on and it's no longer in budget
I went into 300 BLK knowing the costs, and really only wanting to shoot heavy subs suppressed. 9mm is fun/cheaper, but 220 gr hits harder. As others have said, it's not really worth the price if you aren't going to suppress it. So I imagine a lot of people buy it because of the hype but lose interest fast because of the price.
I reload berry's 220gr at ~1050fps for under 30 cents per round, and they sound just like a nail gun. But that's also because I'm using the fastest powder I can with a captured buffer spring and an adjustable gas block to tune it perfectly.
You can also get some pretty nasty subsonic rounds for HD.

I'm a little late to the party, but just wanted to offer my $0.02. As an early adopter and member of the 300BLK cult, I thought I might have a little more insight into the caliber and its relevance on the market. The caliber was designed at the behest of some in the Special Operations community. The short version is that in an SMG configuration, basically all the SpecOps community had was 9mm. An M4 with a signifiantly shortened barrel, chambered in 5.56 was, well, anemic at best. 5.56 is already a weakish round, and when you lop half of the barrel off, you create a lot of light and sound and significantly lessen the effectiveness of an already suboptimal man-stopper. So AAC partnered with some in the community to develop a .30 caliber round that would hit harder than 9mm and function in a short barreled M4. The result is the 300BLK. It does exactly what it was designed to do...burn clean in a 9" barrel (something 5.56 absolutely can not do) and hit harder than 9mm (which it does). Suppressing the round was icing on the cake given it's clean burn in a 9" barrel. Suppressing a 5.56 in a 9" barrel is practically worthless...and will ruin most suppressors anyways.
In short, no, it's not the best or the baddest round out there. 6.5 and 6.8 way outperform it past 200 yds, as does 7.62 (but you couldn't get that in an AR at the time...and even now that you can, in a 9" barrel, you still have tons of blast and reloading 7.62 to subsonic is trickier because the case is bigger.) Some have glommed onto the caliber because of it's proximity to SpecOps guys and they want to be HSLD. So if that's the criticism, fair point. But as a purpose built caliber, it succeeds in every single thing it was designed to do. And for me, in a home defense weapon, a suppressed SBR in 300BLK is hard to beat.
Lastly, as to the 300BLK just "copying the 300 Whisper"...eh, you're kind of right, but not really. 300 Whisper was/is a wildcat round and didn't have any SAAMI data. Given that AAC/Remington were going to market the round commercially, obviously they needed SAAMI sign off. And technically the 300 whisper's parent cartridge is a .221 Fireball while the 300BLk's parent case is .223 Remington. So, I mean...yeah, they're similar, but it's not like AAC just copy/pasted the 300 Whisper, but to say that they weren't inspired by it? Yeah, that'd be a little disingenuous.

220 grains at 1050 is perfect for what I am looking for but with a 10.5 inch barrel. What barrel length are you getting this with?I went into 300 BLK knowing the costs, and really only wanting to shoot heavy subs suppressed. 9mm is fun/cheaper, but 220 gr hits harder.

Suppressor + Reloading is what’s sustainable.
P.S. .300BO Subsonics go Sonic out of a 16” barrel.

8" with 8.5gr lil gun. But I had to enlarge my gas port, and run a carbine buffer weight to get BHO. Very clean rounds.
Not if you're loading them correctly. After 9", a properly loaded 300BLk sub will have no further acceleration because all of the powder has been burned. In fact, in a 16" barrel, a 300BLK sub will be slower than it will in a 9" barrel due to friction from the rifling. This part of what gives people issues with cycling subs in a 16" barrel without the additional back pressure afforded by a suppressor.
I was referring to the off-the-shelf Remington Subs I tried previously: I suppose I should have prefaced.
It completely does in my 14.5” .300.
Why do I have a 14.5” .300 You say?
Why One of our former .300 members who had it in his name put one together for me a few years ago.
