Being new to suppressors I was wondering how a 9mm and a 300bo compare in sound out of a 16 inch barrel. I really don't want to get into another round as I have just consulated to. 22 9mm . 22 9mm 5.56 and 308.

The advantage to 300 Blackout is that you get the ability to shoot supersonic loads most of the time but subsonic when you need to.  If you are choosing a round to suppress, subsonic 300 Blackout is quieter than everything but 22 LR.  I prefer 9mm, myself, because you can shoot heavy 147 or 158 gr loads out of your sidearm and rifle whereas the BLK round is strictly a rifle deal.  (no, a 300 BLK pistol is not a sidearm, it is just an SBR without a stock).

That said, if you have only one suppressor, you can get away with getting a quality 30 caliber QD suppressor and using it on .308, 556, and 300 BLK.  If you have a 9mm carbine, you'll need a 9mm suppressor that probably won't work with your .223 or .308, though I think Liberty has one that is rated for slow-fire .223.

Were it me, I would get three suppressors:  A 30 caliber, a 45 caliber, and a .22 lr caliber.  I cover most of the calibers including 44 Magnum carbine and .300 Winchester Magnum.

You have to decide if you want one versatile suppressor (Liberty Myxtic X is probably best option here) that leaves out the .308 or two suppressors that cover EVERYTHING you have or possibly three that cover .22 LR better.

Your choice of host will make a difference as well as whether or not you reload. I can make my 300 BLK loads using Hornady 90 gr XTP out of a Handi-Rifle sound like a mouse fart.




But if you're considering AR platforms, I'll take a 9mm AR over 300 BLK in a heartbeat. From a sound perspective, both are pretty quiet but the ammo costs clearly tip the scales in the favor of 9mm. I can load 5-7 9mm subs for every round of 300 BLK sub and more ammo equals more shooting fun.

Hadn't considered that, but yes, I can load the 158gr round-nosed lead bullets pretty cheap.  I would not shoot lead .30 cal bullets through a mouth-sh**er like the AR-15 with a DI gas system.

totally a tangent at this point, but I've been reading more and more about people shooting lead coated rounds through their AR's.  I still don't get a warm and fuzzy on it just yet, but if it's another option talk about a way to really lower the cost of shooting!

Years back I had a gas-check 150gr lead bullet load for my SKS.  This was in the early 90's.  I never noticed a hint of leading anywhere and that was in the days before fancy bullet lubes.  Coated bullets are the bees knees... but I do love me some beeswax-based bullet lube!  No beating that smell.

Lots of good coated cast bullets out there for very cheap. I have had success with MBC 245g and Palmetto Projectiles 203g. $.011/round is pretty cheap and no leading in the barrel. 300 BO is definitely a reloaders cartridge.

I've tried coated lead bullets and had terrible time with excessive leading.  I have switched to FMJ only now as a leaded up centerfire can won't be that easy to clean down the road.  

I may try them again once I get my MysticX but for now it's a no go.

If you are shooting both out af an AR platform the 300 will be noticably quieter.   The 9mm has a significant pop out of the ejection port due to the blow back design.

I am going to try a 12 oz buffer on mine to see if that quiets it down.

May I ask what particular brand of coated bullet you were using?  This seems counter to what I've read about other people.  I do not have a significant amount of experience with coated bullets... yet.  I found Missouri Bullet Company and they seem to have a better selection including 300 gr .44's for my CVA single-shot.

I know it's all subjective, but I have had exactly the opposite results.  300 Blackout port pop was much louder than that of the 9mm carbine.  I am using an Octane 45, though, and there is much less back pressure, I'd imagine, than a 9mm can.  I'm also using 147gr loads that are subsonic out of my 16" barrel.
