Suppressors 338 Lapua: Standard vs Subsonic

[KYS]

This is not the best quality video or sound BUT I wanted to post it up anyways. My friend shot this when we hit the range earlier today, it was about 14 degrees and windy. We had 10-15mph winds from left to right. But we were sighting in a few rifles and I decided to grab a few subsonic rounds to try out. At 100 and 200 yards they did fine, shooting about 3 mils low and 1 mil to the right on my 200 yard zero.

Here is the video, enjoy: There should be two shots, I hope it downloaded all of it...

Sounds alot quieter than the last 338 I was around. Nice to know myself and wildcat78 werent the only ones out shooting today. I gave up playing with subsonics in my 308. What kind of load are you shooting in the 338?

Re: 338 Lapua: Standard vs Subsonic

Which load? Standard or subsonics?

I think I heard a sonic crack with the subs or am I hearing things.

it was probably the bullet splitting the wood target holder. its a 1 inch thick backing that had got wet, froze and then we started shooting it. Its much quieter in person.

300zero is a new member here, he filmed it. a good buddy of mine and he actually got me into the precision rifles.

Those subs don't sound that quiet to me.

Re: 338 Lapua: Standard vs Subsonic

you will just have to take my word for it. sounds like a 22 pistol going off. For a big magnum caliber.... thats pretty damn quiet. You have to remember, its a cell phone video, not good audio quality.

It will be louder in the cold as well. It was about 14 degrees.

Which can are you using on your 338LM ?

Re: 338 Lapua: Standard vs Subsonic

I can tell you that the subs where a lot quiter than standard loads through his can. I was using the camcorder feature on a phone. It was sick son!

To all those questioning the sonic crack of the Subsonic bullet, be advised temperature/air density/altitude dictates the speed of sound, as an aside it sounded like I heard a crack also.

Re: 338 Lapua: Standard vs Subsonic

Are you sure altitude has an impact? I've heard some relatively informed folk say it's all humidity and temperature...

Re: 338 Lapua: Standard vs Subsonic

Sorry - the <span style="font-weight: bold">only</span> thing which affects the speed of sound for all practical purposes is the temperature. Humidity has such a minor effect that it can be ignored. See:

Re: 338 Lapua: Standard vs Subsonic

never disputed that temp didnt have an affect on the sound. It does affect it
It was very cold that day and I can assure you the Corbon subsonic ammo is extremely quiet. about as quiet as my suppressed 308 bolt guns. I am working on getting a better idea. hoping for warmer weather soon, and better video equipment!
