Keeer Boooom ????
When deer hunting and some someone shoots a distance away you hear two sounds. The first is a keeer followed quickly by a boom.
Can anyone explain what I am hearing?
Thanks

If I'm not mistaken, one of those noises is the powder-charge detonating, the other is the sonic crack of the bullet.
Given that the bullet would arrive at or pass your position before the firing-noise would, my guess is that;
"Keeer" = Sonic crack
"BOOM!" = Firing
Stand up and fight, or lie down and die; for it is better to burn than to ever fade away.0 -
The first noise is the sound of the bullet hitting the deer. The bullet travels much faster than sound, so if the deer is closer to you than the hunter, first you will hear the bullet hit the deer. 0 -
the sound(s) that you are describing are the ignition of the ammo - the sound of the bullet hitting the deer is a distinctive THUMP that everyone in the woods will comment on later because it is a fairly unusual and distinctive sound 0 -
In mountainous country, I always hear an echo about a second after I shoot. But I always hear that Whump.

He's got it. If you fire a suppressed firearm, which only quietens the muzzle blast, using supersonic ammunition you'll recognize the "keer" sound of the bullet creating a mini sonic boom. It's a lower frequency sound than that of hot gasses hitting the atmosphere at the muzzle, therefore it sounds distinctly different.
This is also apparent when you fire a .22lr across an open field. With little to reflect off, the minimal muzzle blast dissipates quickly and allows you to easily hear your bullet going through the air. It sounds similar to an echo due to the secondary sound originating from down range. You don't get this effect with .22 shorts or longs, which are subsonic.0 -
Exactly, it's the bullet breaking the sound barrier followed by the muzzle blast.

That "Keer"-sonic sound might obly be found in weapons in the US.
As I've been silencing/supressing a lot of guns and testfiring them as well, I never could tell the difference between the sonic crack and the explosion itself.
It all sounds like a BOOOM to me.
As sound travels at a certain speed, regardless of it's origin... explosion or sonic-crack, the sonic crack will never reach you before the powderexplosion does.
I agree, that the sound is indeed the projectile hitting the deer or something else, that gives a strange OMMMMPH - and that something else is between you and the other hunter.
Now don't worry, it doesn't have to be directly in between the two of you. =o)
Don't do anything that I've allready done - That'd be just plain STOOOOOOPID.

[8D]Hey , when you're in a valley-CRACCK----UMPHHHH-or CRACCK--OOOOPS-iT'S ALL RELATIVE! agree[?][?][?][:D]
On your mark-get set- go away!!0 -
If you've ever been on a battlefield you'd know there's no sonic crack to a bullet's passing; it's more like a ffffft. You're hearing different phases of the sound caused by the exit of gases from the muzzle. 0 -
I believe Dunnedan has it right also. Shooter doesn't hear supersonic explosion due to powder explosion masking it. It IS very evident to others "downrange" of the shot (Doppler effect?). Could always tell when my Dad shot his .243 in my direction by the loud, double "CRACK-BOOM". Unfortunately for him, there was seldom a "whump"![:)]

HOPEFULLY YOU WILL ALWAYS HEAR BOTH SOUNDS, WHATEVER THEY ARE, AND WHATEVER ORDER THEY ARRIVE. 0
