Subsonic .22 ammo

Teflon · Sep 10, 2014

Anyone have a good spot to buy this, either online or in person?

Engage Armament · Sep 10, 2014

We have RWS Subsonic in stock at $9.99/box of 50.

Remember, pretty much all the "standard velocity" is subsonic. High velocity is supersonic.

Been laying in mucho pounds of Gemtech Silencer Subsonic lately. Been in stock more often than not. Buy it by the case when you can. Great stuff!

Am I the only one that doesn't like to shoot LRN through their suppressors?

Hmm, harder hitting???

42 grains at 1020 fps is 97.1 ft-lbs of energy.

40 grains at 1050 fps (standard velocity) is 97.9 ft-lbs of energy.

So which is harder hitting??????

Huh? The 555 box of "Standard" Winchester white box ammo I have is 1280 FPS. The speed of sound is about 1125 FPS.

Soooo, standard is supersonic.

No, what you have is high velocity ammo. Standard velocity ammo is going to be in the 1000-1100fps range and thus subsonic.

I have the same problem locating the cci subsonic anywhere local. I always stock up when I go to the Harrisburg or York shows. There are two guys there that always have it, and it's usually around $7.99 - $9.99 a box.

None of the bulk boxes of Winchester or Remington 22LR say "high velocity" anywhere on the box or in their marketing materials and they all have muzzle velocities higher than 1125 fps. :shrug:

And that means what? Absolutely NOTHING! Why don't you do a couple min of research on STANDARD velocity .22 before you throw out bs info. Let me know what you find.

Sorry for your butthurt. :lol2:

No butthurt here. Just pointing out the the stupidity of some. :tongue01:

This went bad at supersonic speed.

No no no, it didn't go bad at supersonic speed because supersonic wasn't written on the box...

Sorry, but your answer is incomplete. Air temperature must be considered when calculating the speed of sound. Without knowing the temperature at which the round is fired, the crack you hear (breaking the speed of sound) can occur much lower than the 1125 fps, thus making standard velocity 22LR ammo supersonic.

ps Humidity and altitude will also make a difference.

Like your own?

Standard velocity

"Standard-velocity rounds have a slightly supersonic muzzle velocity of around 1,125 ft/s (343 m/s), and a "normal" bullet weight of 40 gr (2.6 g). Standard-velocity cartridges generate near or slightly supersonic velocities. These rounds generally do not develop these velocities in handguns because their short barrels do not take full advantage of the slower powder."

While it maybe incomplete when throwing in extremes, my answer is not incorrect.

Okay, whatever you say. But the text books, the folks that write the text books and everyone I know, realizes that the speed of sound is not constant, but you believe what you want. However, you are wrong. Deal with it.

How about you also post the section on HIGH velocity ammo as well. This is where your box of Golden Bullets will fall (1260fps?) thus making your claim that they are STANDARD velocity wrong.

Your quote also does nothing to disprove me when I said .22 in the 1000-1100fps range is subsonic. Its only addressing ammo that is on the edge of being supersonic. Any STANDARD velocity ammo I have come across has been well below in the 1050fps range making it subsonic under most common conditions.
