300 BO is more like a handgun round than a rifle round. I reload them, both sub and super and use pistol powder.
All subs are like handgun rounds unless you are pushing 300+ grains of lead.

The above puts it all in perspective concerning suppressed.
Does anyone hunt with subsonic 300 BO rounds? I’ve had my 300 BO since April of this year and have only shot super sonic rounds until my last two visits to the range.
What have you done to reliably shoot subs in your firearm?

while on the subject , how much louder are supers than subs ? i know it's all relitive , your supressor and all , just courious .
More gas making noise as well as the crack of the bulldog going supersonic.
For 22lr and a good suppressor a subsonic round out of a bolt gun produced in the range of 104-108dB of sound. A HV bullet produces between 118-122dB. That’s a bit more than 10x louder (sound is a logarithmic scale).
For the much larger and heavier bullet of a 300BO you are looking at probably around 114-120dB for a subsonic round with suppressor. Supersonic likely 130-140dB.
For a distant observer a subsonic suppressed 22lr you might not hear 100yds away over suburban background noise levels. For an HV 22lr suppressed it might take 200-300yds before you wouldn’t hear it at all.
For the 300BO that means about 200yds suppressed subsonic you likely wouldn’t hear. But supersonic it might still be audible at 500-600yds.
Now that’s “being able to hear”. It loud gun shot when you get close to those distances.
That’s assuming line-of-sight from listener to the source of the sound. Buildings, trees, etc will middle or more.
A regular gun shot is 155-170dB and could be heard more like 5+ miles away in open terrain.
All those decibel references are meaningless.
Is that Peak Level, Leq, Peak Range, Maximum Level, A weighted, C weighted, Z weighted, unweighted...? At what distance and orientation to the muzzle were the measurements made? What diameter microphone?
If you've never shot a single shot or bolt action 300BO suppressed you're missing out. I use my single shot, one tax stamp Encore a couple times a week to eliminate the groundhogs at a few local farms. I reload a 148 grain cast hollow point over Trail Boss for all my 150 yards and closer hunting areas. I load the new Hornady 190 grain Sub-X over CFE BLK for the areas that require me to lob in some longer shots.
This week I killed 7 at a local farm in about 2 hours. The two furthest shots were 305 and 308 yards (dialed 34moa with 100 yard zero). I missed on the first shot due to some wind at my back. Dialed down just a hair and took them both on the next two shots. The other 5 were between 107 and 238 yards with only one making it to his hole.
That’s awesome. Good shooting too!
How is it one stamp, is that a brace or integral suppressor?
It's a 10" form 1 suppressor that I pinned and welded to a 9" Bull Berry barrel. I refuse to SBR anything due to the crazy expectations of having to notify the ATF if I want to travel out of state.
Actually it isn't. AAC was able to get the 300BLK in for SAAMI spec, because J.D. Jones chose not to do so for 300 Whisper. Same cartridge, yes. Rip off, no. In the end SAAMI spec rules the day.The Blackout is a rip off of the .300 Whisper .
The .300 Whisper was invented by J.D. Jones specifically to outperform the MP-5 SD with 147 subsonics .
Having done that , he then explored the hunting capabilities to seek extra markets for it , and found it did great . J.D. killed literally truck loads of Whitetails with subsonic 220-250 gr in testing .
