Is your HD rifle suppressed or is ear protection the plan or both? Poll.

Forgot about the 300 blackout factor. That platform is certainly Suppressor for sure.

I have always joked that the deafness acquired from shooting firearms indoors beats the deafness acquired from being shot by firearms indoors.

That said....plenty of solid tactical reasoning to preserve your senses. 300 blk 220gr subs suppressed barely interrupts a conversation. That's my go-to. I don't keep kit in the bedroom anyways, it would have to be one serious home invasion to send me to the safe.

What's a "Berger" bullet?

That's my thought. A can is still about as loud indoors as shooting a 9mm pistol in my experience. Who knows for sure? Unless someone has had to shoot it out with an M4 in his house, we're all just speculating was the best answer is.

An unsuppressed 9mm Para handgun is typically >160 dB. A MK18 with a SureFire SOCOM556-RC2 is ~145 dB (~138 at the ear outdoors). That is a huge amount of difference in volume. The human ear is pretty bad at distinguishing loudness unless right next to each other. Remember that a 6 dB increase corresponds to a rough doubling of the sound pressure (thanks to tangolima for the correction), so a 15 dB difference is huge in terms of how much damage your hearing might sustain. At 145 dB, the sound wave pressure is at ~356 Pa; at 160 dB, we're at 2000 Pa.

3dB is 40% increase in pressure, not double, I'm afraid. It is 20*log() kind of deal. 6dB to double pressure.

Only tried it with a M4-1000. Ear ringing was comparable to firing a 9mm in an open outdoor area. Unscientific, I know. But the closest thing I can compare it to.

The gist was that Supersonic fire indoors is far from hearing safe.

I had to look it up.

It's a hunting bullet meant for 2500 fps + velocity.

At .300 BLK speeds, probably SS as well as Sub, it's going to make a smaller wound than 115 gr 9mm FMJ and penetrate far more building material. I don't understand why one would choose this.

I keep a 11.5 suppressed SBR as my emergency rifle. That being said, I think I would PREFER to have the same rifle, or even a 13 inch .308 without suppressor and good active ear pro. I think the idea a of a semi auto flash bang generator would be pretty effective (presuming you put in a little time under enclosures to get yourself used to it). I just don't want to be fiddling with ear pro when someone is kicking in my door.
