Hi everyone,
I’m looking to purchase a Noveske .300BLK 8.2" SBR. However, Noveske warns that subsonics can have issues as the action gets dirty. This will primarily be for home defense, so that worries me.
Is this a valid concern? Does this happen often? Is there a round count that these problems start to arise?
Much appreciated for any help you can provide.
Subsonic is a little more sensitive when the action gets very dirty and or dry. Keep it well lubed and you shouldn’t have any issues.
Perfect. Thanks Todd!
Biggest concern I would have is using sub-sonics for home defense. By its very nature, it’s under-powered, like a handgun. Worse, is that the common sub load for 300blk is a 220gr SMK, which won’t expand. Use supersonics for home defense.
This x100. Subsonics are fun, but they aren’t what you want to use to defend your life unless your job requires it.
Check out the watermelon tests towards the end of this video. It’s not scientific, but it gets the point across, I think.

ETA: I have had no reliability issues whatsoever running hundreds of subs suppressed without cleaning out of my 8" Noveske barrel.
Great to know, guys. Much appreciated. Very new to this whole 300BLK thing.

Look at Remington Accutip or Barnes VOR-TX (black tip) for defense.

Will do! Any other loads to look for?
Nope. Those are the two crimped, expanding supersonic 300 BLK loads out from a major manufacturer. Corbon and the like also have loads with the VOR-TX bullet, but I’d stick with the Barnes brand since it was extensively tested.
The Hornady 110gr V-MAX performs well on target, but it is not crimped. I had a bullet drop out of a round after loading a mag on a closed bolt once. That’s not a problem for hunting, but it’s bad juju for HD.
UMC is crimped also.
If the Barnes is too expensive to fill multiple mags, I would fill six with UMC and one with Barnes.
I use subsonics simply because they suppress well… and I run a suppressor on my HD gun…
but those are valid points…
300 BLK supersonics also suppress really well, being plenty quiet to reduce hearing loss indoors. Plus, there is no concussion whatsoever.
I run Pink Tips and a 762-SDN-6 for HD. Baring Pink Tips, I’d probably run my first mag with Remington AccuTip for faster expansion, with remaining mags filled with Barnes VOR-TX in case 30 rounds didn’t get the job done (yikes).
AccuTip is better than PinkTip as they are 100% gauged (each round is hand placed into a chamber and if it does not fall out under its own weight is scrapped).
I would run a 3.0 oz CAR buffer with a stardard USGI Colt carbine spring.
This is what I have found to be the most trouble free setup over a wide variety of sub and super sonic factory ammo with noveske 8" and 10" barrel. I have used both suppressed and unsuppressed with all these combos.
