.223 vs. 7.62x39...which is louder?


September 5, 2009, 05:50 PM
Thinking of getting a Saiga in one of these two calibers.

The only range near my town is an indoor 25 yard. I dont get to go to the outdoor ranges nearly as often because they are about an hour away. So most of the time id be going to the indoor.

But im worried about bad the blast will be indoors with these 2 calibers. This one time at the indoor range, a guy showed up with a short barreled M4 type .223 in the port next to me. The blast was so intense I had to put down my gun and step away from the firing line until he was finished. I dont know if it was because of the short barrel, but it was not fun to be standing next to.

Is the blast from the 7.62x39 any quieter/less intense than the .223?

25 yards, what’s the point, any way go with both, however make sure firing long riffles in indoor range is allowed, LR bullets are traveling much faster then pistol bullets 2500 fps for 7.62x39 and 223 depends on the load is about 3000 fps compare to 9mm luger about 1200 fps, many places don’t allow long guns in indoor (pistol) range but they will allow 22 LR

I really don't think for the most part you will notice a difference. There a number of factors including barrel length, type of flash hider, particular loading of the cartridge to be taken into consideration. So one could be louder than the other depending on the set up.

From you issue with the guy in the next port, I don't think it is going to be quieter inside your own port, no matter what you get. My best guess is that you are not going to like either one when shooting inside.

Ain't much point in using either caliber, short-barreled rifle or not, at and inside 25 yards - especially indoors. If you've got to fire both inside and at close range my suggestion would be to go with the 5.56 x 45mm. You should be able to handle it a little better under such circumstances.

Hmm. Maybe I will go with a pistol caliber carbine instead. Starting to seem more practical for my situation.

good choice, and here is something to play with while you at the range :rolleyes:

Indoors either one will be uncomfortable IMO, unless you have about a 3 foot barrel.

Good thinking, Guvnor! If you're starting from, 'scratch' and have no compatibility issues. Take a look at the Kel-Tec SUB-2000 (http://www.kel-tec-cnc.com/sub2000.htm).

(Make sure it accepts Glock magazines - preferably in 9mm!)

And if you arent made of money you can buy a hi point carbine and spend the other 500 dollars on 9mm(which may get you five of six boxes of 50 these days).


Dont be fooled by the display pic, these are the new 995ts models that feel more solid than the 995 classic.

Right for the price range you were looking at saiga KelTec would be a wise choice, Berettas a bit pricey
or HiPoint they run 200 bucks

Both are very loud. I can't say which is louder - different in tone but not really in volume.

A longer barrel will help but only a little.

Many indoor ranges prohibit steel jacketed bullets, and nearly all 7.62x39mm ammo uses such bullets (except for US-made stuff which is usually 3x as costly). It's much easier to find copper jacketed .223 bullets - in fact most .223 ammo except Russian imports (M855/SS109 has a steel inner tip to the core which would also be a no-no for an indoor range).

i have a AR15 IN 5.56,IT DOESNT COMPARE TO MY 5.56 ROMY AK.NEITHER DOES MY 7.62 ROMY AK.i dont know why but the 5.56 ak just flat out makes people ask what the hell is that?its louder,throws a flame 3 to 4 feet long and about 3 foot in diameter,especially wth the winchester 40gr hp varmit loads.even regular 55gr rock.so i think alot of the sound would depend on the gun.

"what excatly does varmit taste like?"

I have shot both at an indoor range and i honestly didnt think that either one was that bad. Ive even shot my 16" Saiga .308 indoors just to test it after i did the conversion because our wonderful Ohio weather wouldnt allow me to get to the outdoor range at the time.

I never had any problem with the noise, just invest in some quality ear protection.
