Anybody try a .300 Whisper?

[Doug]

A buddy of mine is having a rifle built in .300 Whisper. At least a year ago he told me about it, and the research I did convinced me that I MUST have one of these. So I bought a BLR in .223 to have converted, and have been patiently waiting for my buddy to get his rifle back and give me the skinny on it. So far he has been waiting 18 MONTHS for his rifle..........

OK, does anybody have one of these in a NON-restricted rifle? What do you think of it? Is the published information true, ie hits like the hammer of Thor at sub-sonic speeds? And (most importantly) do you want to SELL your gun???? ;-)

Anybody?

Lets see....30Cal.....1100fps.....hits like"Hammer of thor".....hmmmm? My 50/90 Sharps uses a 625gr. bullet at faster speeds and I don't think it hits that hard.

Why would someone want this caliber?

So I bought a BLR in .223 to have converted.

And why would a BLR be prefered over an SPS 700 for a conversion?

Same Bullet as a 30-30........but Half the Velocity !

Hammer of Thor indeed !

Just Funnin thier Doug !
Actually I think the Huge appeal to this round is the low "Report" or lack of it.
For the Noise levels it produces yes it has good smack...Much more then a Good Air rifle anyways.
Kidding

Another Huge Reason for being was to Function in an AR 15 !
Probably the most legitimate excuse for it's existance

Whisper

I don't think there needs to be an explanation of why Doug wants a 300 Whisper. Look at his avatar (Pic of Doug).

If you look at it for more than 20 seconds, something in the mind says " Yup. he's a Whisper kind of guy". In the bedroom or the bush, I am assuming either Whisper from Doug would have the same result.



Merry Christmas Doug

Personally, this all seems like a bunch of work for nothing. I can understand the reasons for the cartridge if you are limited to an AR-15 type platform.

If you're using a bolt gun or another type of action, I don't see why you wouldn't screw on a .308 1-8" twist barrel and chamber it with a 7.62x39 reamer. You could then shoot 240 Sierras to your heart's content out of a factory case.

So many mods when thors hammer is already available in 300WSM

 

[Amphibious]

all this talk of "thors hammer" and its a discussion of .30cal.

whoopy! a medium bore! .30cal suited to being Loki's tack-hammer at best, regaurdless of how fast you push the bullet

 

[John Y Cannuck]

Well, as a guy who shot a deer with a 44-40 at 1200 fps, and was impressed, with how quickly it fell over dead. I have a new respect for low velocity rounds.

The Wisper? Love to try one, it's likely quiet, and accurate, but I'd want to see some penetration tests and do my own trajectory analysis before using one on game.

Hmmm...you obviously don't know Doug
"Whisper kind of guy" he's certainly NOT


Seriously if I remember correctly the Whisper was developed by the military to shoot at less than the speed of sound so it could be used in conjunction with a silencer or maybe not

 

[Jamie]

I shot one state side with a Can on it....all you could hear is a clickhiss.....and then SMACK of the round hitting the target and I think it was pushing the 240gr matchKing


on full auto is was awesome!!!


we have a guy who has and loves his here in Town a 700 with a 20" barrel


I have not seen him in a while to get more info

I have a sub sonic load for the 308 that works well (I use it to teach my wife to shoot very low recoil,not loud and funn to shoot)

I know that several rifles have been made up to various "fish and game" department specs, and the things push bullets all the way through a whitetail front to back.

yes the military and LE versions have suppressors, this is a luxury denied ordinary folks like me.

These rifles allegedly can shoot the heavy bullets like the ones Jamie talks about, where the bullet is darned near as long as the case, VERY accurately and with devastating results.

I WANT one.

yep the 220's are longer then the case....

And a 300 Whisper next to a 223 Rem...

 

[Jamie]

you will need a fast twist barrel i think..

I have a po-man's Whisper - a 10 twist .308 bore 7.62x39


Never tried any heavy/subsonic loads, never really saw the point

It's a CARTRIDGE not a CALIBER..

it woudl be very useful for low noise predator control around the farm...

Actually I think the Huge appeal to this round is the low "Report" or lack of it.

Not as quiet as you think. Subsonic rounds, depending on the powder type will produce a sound signature of about 155 dB or about as loud as a .45 cal pistol. Certainly loud enough that you still need hearing protection to shoot it.

These rifles allegedly can shoot the heavy bullets like the ones Jamie talks about, where the bullet is darned near as long as the case, VERY accurately and with devastating results.

HUH?

Subsonic accuracy is VERY difficult to obtain over short distances. It is almost impossible at anything over 200 yds. And what exactly do you mean by "devastating results"? If you mean a nice smooth .30 cal hole through the target then yeah, its "devastating" but if you mean any actual tissue damage then no, it is dismal compared to conventional high velocity bullets.

I know that several rifles have been made up to various "fish and game" department specs, and the things push bullets all the way through a whitetail front to back.

It is true that subsonics penetrate to an unbelievable degree but the wound channel they produce is pretty dismal unless they have the time to yaw sideways, which in a typical broadside shot they don't.

the Whisper was developed by the military

All of the Whisper series of catridges were developed by JD Jones of SSK Industries. The military had nothing to do with it. The 300 Whisper was specifically developed to function through the AR platform.

but I'd want to see some penetration tests and do my own trajectory analysis before using one on game.

Subsonic: Penetration is impressive. Terminal ballistics are not. Trajectory sucks.
Supersonic: Comparible to 7.62x39

 

[Doug]

Here is an excerpt from a note my buddy sent me:

After receiving field reports, one thing is clear, you have to be
intimately familiar with the trajectories of the heavy 220-240gr bullets.
Shot placement is also very critical, and they have found, even with
subsonic velocities, although we are now working with a different priniple,
and not kinetic energy, from hi velocity, those bullets, to include 180 RN,
will go thru a WT deer from end to end. Same principle as a Black powder
405 gr 45-70. No tissue damage from hi speed, just penetration...and a big
hole.

It's a CARTRIDGE not a CALIBER..

I just got the clip/magazine nomenclature straight in my head ......... Now I'm on to caliber/cartridge.

it woudl be very useful for low noise predator control around the farm...

So basically the 300Whisper was designed as a low noise varmint caliber for the AR rifle?

One can always load a 125gr to fly around the 2300fps mark...One guy presented a deer load of 18.5 gr of H110 and a 125gr ballistic tip using reformed 221 brass, and a 15" contender barrel.
