The only real purpose for this round is that it can be made subsonic.
Other than that a 6.8spc or 6.5 grendel is a far better choice.

.30 Blackout Cartridge ?

Because said owner of the LGS knows the average gun guy drank the .30 caliber koolaid his daddy handed down to him. Same as thinking the 350 Chevy is the epitome of all engine designs.
If the .300BO has a supersonic application, it would be as a shorter range deer and hog gun, and you can shoot it that way with no alteration from the suppressed mode. Just load the higher powered ammo. That will extend it's lethality out to about 250m, where the BC and weight finally degrade it to the point of being a holdover problem. Most .30 intermediates are already known for that, X39 or .30-30.
You CAN reach out another 100m with 6.8 or 6.5. On lighter game, both will go out to 600m, although that's prairie dog range. If it's high round count consumption, 5.56 at 4.50 a box will always be the cheap leader, it's the advantage milsurp has over any commercial ammo. Production is based in the milllions per year, plants like Lake City have been running 24/7/365 for nearly a decade. 5.56 ammo is growing in the number of countries using it as the M16 is adopted overseas.
For reloading at home, whatever floats the boat, they are all about the same. .300BO could be loaded sub or super, so can the others, it's more about how you intend to shoot than just pressing out cheap ammo on it's own merit. Buy components in large enough bulk quantity, or forego premium precision components, and most ammo gets real cheap. Enough reloaders shoot 2-3 times as much as shelf only shooters. They are also getting their pet loads twice as accurate.
Those are real reasons to shoot .300BO, downrange performance on the chosen target. Do the ballistics fit the job you need done? Fine, if not, choose something else. Just because it's new on the market doesn't mean it's appropriate. Rem .30AR isn't all that, either.

Rsilvers, out of curiousity, do you happen to know:
1. the impact velocity of those 110gr Barnes TSX rounds?
2. what kind of penetration they achieved?

The reason for the 300 blackout over the 7.62X39 is the angle of the neck on the 7.62x39mm, (hence the large curve to the AK magazine.) Also the 300BC has a wide range of bullet weights and with modern powder and design of the cartridge it performs very well with short barrels, (you should see the results of the Rem 700 sniper package with a 9 inch barrel!!!) It's not for everyone. It was designed with a specific military purpose. If you want to compare it to a hunting round it's similar to a 300 whisper T/C.

when I wanted a 30 cal ar15 i looked at all of them. I looked at ammo availabilty loading component availability and performance. My buddy had a new 6.8 and it was high on the list but brass was just to hard to come by. Same goes for the alexander arms rounds. the wisper was a bit better as brass could be made by necking up 223 but it was a time consuming project as it has to be necked up gradualy and the necks can get thin. I went with a 762x39. Brass is everywhere. Its ballistics are very close to the others. I can buy wolf ammo for days im at camp and dont want to pick up brass and its cheap enough that a guy can sock away a few cases for just in case. I bought a complete bushmaster carbine. I didnt want to build one because i heard some complaints about reliability and i wanted to have a service dept to fall back on and bushmasters service reputation is second to none. It had a bit of teething problems. First was magazines. the ones supplied with it were made by c products. the first batch of cproducts mags were a 100 percent reliable. I had also bought 10 new cproducts mags. I was having reliablilty issues and contacted bushmaster. they sent me a return shipping lable and told me to box the gun up with all of my mags, even the ones that didnt come with it. They did some work on the feed ramp and replaced all 12 mags with the newer c products mags. After that id say it was 95 percent reliable. Still have a couple mags with issues though. I saw someone on the internet who said to switch mag springs out for wolf extra power ak47 mag springs. I did that to all of my mags and the gun has yet to miss a beat with any ammo including handloads and wolf black box and the newer wolf. It shoots 2 inch 5 shot groups at a 100 yards wolf black box and with a handload using hornady vmaxs shoots under moa. Point of all of this is dont believe all the storys you hear about the 762x39 not being reliable in a ar platform. Most of it is internet bs thats passed on by guys that have never owned one. One guy says its so and everyone that wants to come accross as a gun expert picks up on it and posts it to look like there knowlegable. Would i shoot a deer at 200 yards with it. Probably not. A 150 is more realistic for a max range. In a pinch though if a guy had to put meat on the table or protect himself from someone it would surely get the job done. Its surely minute of man at 200 yards even with wolf.
All these 300 Blackout cartridges appeared on my kitchen table today. I have to wait until next week to shoot 'em. (I know, crappy cellphone pic)
BTW, Lee Pacesetter dies are crap. I'm still using the seater die so that I can have one for the 225gr bullets and one for 125gr bullets. That will be replaced once I need to order something else. The FCD is useful however.
