As it states above, are there any good sites to purchase 300BLK in sub/supersonic? I plan on buying in bulk. I usually only buy 7.62x39, but places that carry surplus ammo don't seem to carry 300BLK.
I got really lucky right after I bought my ddm4 in 300 blk and scored a box of 250 rounds for $167 from freedom munitions. I have been able to locate absolutely NONE since then outside of seeing them on gb for $2 a round plus. My dad and I recently got into reloading and the components are far easier to find than the 223 stuff. I have about 8-900 bullets ready to be loaded so I think Im set for a while. If it wasnt for that Id sell the rifle bc its really that hard to find right now.
I've also been unable to find ANY subsonic. I have a small stash but not enough to make it worth my while to swap in my Noveske barrel. Good luck w/ the search.
The .300 BLK supersonic as well as .300 Whisper are exceedingly rare these days. In the last 4 months I've seen ZERO subsonic .300 anywhere.
You might want to think about loading your own. The brass is not that difficult to make from .223/5.56 cases. The .308 bullets are (relatively) easy to find. It doesn't really take as long as you think to put together a couple hundred rounds. I just do it instead of wasting time paying attention to the TV.
But unless you are using a suppressed rifle, there is no real advantage to the subsonic. I have a .300 BLK AR and I would buy subsonic if I found it but only because it's .300 period!
I got 100 rounds of .300 Whisper from Cabela's a few weeks ago. A guy here on INGO advertised 200 rds of .300 BLK and we made a deal. I was at Bass Pro in Clarksville last month and they had a few boxes of .300 BLK on the shelf and I kick myself for not picking it up. But I'm sure it's long gone by now...
By the way, if money is no object, there is always plenty of it on GunBroker.com. But be prepared to pay $2+ for supersonic and nearly $3 for subsonic.
