M4/M16/M249 question.

[kotay]

but hearing the high pitched cracks is a bad bad thing, more than likely means that they could have a bead on you.:shudder

Being 3 metres under the target with the bullets going dead overhead will give you that

Oh Oh,

Not the annual beer hunting party for the majority of hunters out there.

Last weekend in HK the bar ran out of Heineken. I had to settle for Stella Artois - taste like drain water.

The reason why a 105mm seems louder (I am assuming that you are talking about a tank maingun) versus a 155mm howitzer is due for two reasons, one is due to propellants for tank ammunition (flatter tragectory), the other reason is due inpart because a howitzer more than likely is pointed skyward when launching a round causing a shift in noise decibles. You would not want to be near a 155mm firing in the point blank mode, the concussion does have the capability to cause extreme medical complications to your body if you are not behind it.

Also, a weapon with a muzzle brake will always be louder versus a weapon without one, thus the reason why they are not used on tank mainguns.

So the M16 is louder than a .50 cal machine gun?

So a detail of 12 people firing from 300m away would sound like many whips cracking, quickly followed by the "booms"

The Bundeswehr, at least 10 years ago, actually still taught noise/fire discipline for that. Entire squad - or each halfsquad - fires on signal on preacquired targets in order to prevent the enemy counting off your soldiers. Single crack, single boom.

Thinking back on it, the only difference I ever noted was when the thing whizzes pass your head, especially after a ricochet. Bigger the bullet, bigger the whizz wherr sound (and no, it is not combat experience, It is living amongst really bad deer hunters)

cheers

gday mate! Yeah, also when in the butts party at the rifle range, you get very used to the sound of bullets passing very close over head, and rickocheting in the mounds at times. When you hold a figure 11 target up, and walk left to right to present a moving target, you can definatly tell the difference to 5.56 and 7.62, esspecially when the round hits the pine post that the target is attached to! The 7.62 is a much harder hit, and louder crack, the 5.56 is a very deffinate whip crack,sounds considerably faster....cause it is!

Louder than a M2 50 cal, no way.

At butt party I could barely feel the 5.56 passing through the thin target board. What about the 7.62?

 

[F-15 Eagle]

Louder than a M2 50 cal, no way.

I thought so, although I agree the 5.56 is as loud as the 7.62 NATO but not the .50 cal.

Here is a video I found on youtube showing off the SCAR-L in 5.56 NATO and the SCAR-H in 7.62mm NATO. The 5.56 NATO is almost as loud as the 7.62 NATO. The 7.62 NATO is still louder but not by much. The 5.56 NATO and the 7.62X39 Soviet for the AK-47 are both equally loud.

The percieved volume has way more to do with the weapon (length of barrel) and muzzel of the weapon plus the type and amount of propellant used than the calibur per se.

I'm with Old Faithful - it was definately possible to distinguish the difference between a 7.62 SLR and a 5.56 M16.

It depends on what type of 7.62 your talking about. I don't think anyone can tell the difference between a 5.56 NATO and the 7.62X39 Soviet but if your talking about the 7.62 NATO then yes it is louder but not by a significant amount.

SLR to my knowledge was never chambered for 7.62 x 39 - so yes, 7.62 x 51 standard NATO.

 

[Driller]

I know this is sorta off topic but is there a discussion on weapon replacements for certain countries ie. Australia and USA?

I know I was just comparing the noise levels of the 5.56X45/7.62X39 and the 7.62X51 NATO.
