I'm wanting to buy another suppressor for my long range rifle because we live in an area with houses close and I don't want to give my neighbors reason to complain however I'm wondering if the bullet crack is louder for a .308 bullet going 2700fps than out of a .22 suppressed going 1200fps? Or is the "sonic boom" the same no matter how fast the bullet is going?

The only dumb question is that which is not asked.
Southwest Ammunition loads factory subsonic ammunition.
If you've got the .22 and suppressor running already you need to pic up some subsonic .22LR ammunition. Remington subsonic is usually readily available and CCI quiet is out there to. Won't produce any more noise than a pellet rifle.

Re: Bullet crack
I shoot CCI standard velocity through my Spetre and it's accurate and quiet, as you say, as a pellet rifle. All of my guns that are threaded like the CCI standard velocity however I've noticed that I get a pretty good crack shooting the high velocity and was just wondering if it would be louder with the full house .308 Winchester load. Thanks for answering my question.

Re: Bullet crack
Yes a larger object displaced more air/shockwave so it is louder. It is only loud durring the flight time, so the flight time of the bullet to the target is less than half so the duration of the sound is less. No matter what if you are going to shoot there, your neighbors will prefer silenced to non silenced.

Re: Bullet crack
David, one cannot judge sonic crack duration by time traveled to impact. Rather it is a complex calculation based on reflective surfaces, sound deadening surfaces and overall topography. In a suburban setting, that can be a very long reflective cycle.

Re: Bullet crack
22lr will be much more quiet suppressed. But my 308Win with Xtreme Shock subsonic ammo is just as quiet.

SW subsonic 308 ammo didn't work at all for me.
Savage 10 FCP. I might as well have been throwing rocks. Neither did EBR Thumper ammo.

Re: Bullet crack
I thought suppressors suppressed muzzle blast and sub sonic ammo suppressed the crack.
Looks like you want both to make the neighbors happy.
BTW, have they complained?

Re: Bullet crack
Both the size of the object and it's speed affect the magnitude of the sonic boom. An extreme example here: http://www.youtube.com/watch?feature=player_embedded&v=-qhc2lXCT9c
I would say that a suppressed 308 rifle sounds about like an unsuppressed 22lr to give you an idea of what to expect.
Make sure that before you try subsonic ammo through your suppressor that you verify your rifle will stabilize it since subsonic ammo usually uses heavier bullets.

1200 fps .22 will crack. 1100 will be subsonic.

"I would say that a suppressed 308 rifle sounds about like an unsuppressed 22lr to give you an idea of what to expect."
Better not. No quality suppressed .308 is going to sound anywhere near an unsupressed .22lr. I hear this way too often and it makes me think there is a boat load of crappy .308 cans out there.

EBR Thumper is not great ammo for outside of 50 yards. I have had success with Xtreme Shocks ammo. But really your best bet is to load your own and see what the rifle likes.

Re: Bullet crack
I have a SS sparrow. I shoot CCI standard velocity in both my CZ rifle and Ruger 22/44 pistol.
My pistol is much quieter because there is not crack of the bullet. I thought the rifle should be quieter but it's not.
Has anyone else seen this??? I just ordered a brick of CCI quiet, will this help the rifle?

I have not used that CCI ammo, but are you sure that the bullet is not supersonic coming out of your rifle?
When I used subsonic ammo in my 16" 10/22 it was noticeably quieter than my mkIII. However, the results were reversed if I used federal bulk pack ammo because the bullet would go supersonic out of my rifle but stay subsonic in the mkIII.

Bingo. The 22 ammo gains velocity in the longer rifle barrel. Odd that it went supersonic, though, CCI SV stays sub even in my rifle. Much quieter than my 22/45. Try CCI subsonic...although CCI quiet will do well, I just have doubts about the accuracy. Good Eley match ammo will cure that, though. Stays subsonic and shoots really well.
Edit: I should say I have a bolt action 22 rifle, so that adds to the quietness. Also SS Sparrow.

Shooting subsonic .22 loads out of a 20+" rifle barrel can be pretty damn quiet even without a can. On the other hand, shooting Minimags from a Beretta 21A is going to be surprisingly loud...

Re: Bullet crack
So, I'll say no.
An excellent .308 can with disciplined subsonic .308 will not sound anything like any supersonic .22 at any time. It will sound unfirearm like and should be a "thonk" (muted hammer in wet mud, all low frequency with minimal attack and no decay) that would leave another on the other side of, lets say two story house, with the impression that a trunk on a fine car has been closed correctly in the driveway. The kind of sound that in and of itself would not be considered as in any way atracting attention. This is why one turns off the gas in a gas gun, locks out in a blow back, doesn't work the bolt in a bolt action, etc. left alone and in the absence of any following secondary action noise a sub .308 through a great can will be astonishing.
