Anyone with .302 Whisper experience?

[shuter]

Just ordered an Encore rifle (16.25" barrel length) from SSK, and bought a can. This is my first subsonic endeavor. Hope I made a good choice! Went with the .302 because of better supersonic capabilities, should I ever choose to use it that way, and JD said it's just as good for subsonic as the .300.

Any input would be appreciated.

see ya

[m21black]

anybody ever hear of a 302 whisper?

[kurtz]

the Whisper range has been extended with the .302 Whisper (7.62 x 38), lntended for chambering in guns designed for the 7.62 x 51....it's kinda like a .308 winchester short.....(see pic)

The 302 looks similar to the 30BR. I have a wildcat similar to this that I put together a while back. Mine is mostly just a shortened 308. I get about 2600 fps with 150gr bullets if I recall correctly. The subsonic loads work pretty good but not as good as the 300Whisper since the powder space is higher. I wanted a more dual purpose cartridge and got it with this solution.

to .308. It's a better solution for single shots like the Encore, according to JD, and gives a little more powder capacity for supersonic.

I'm guessing it may be a LITTLE louder than the .300 Whisper? Don't know for sure?

Any updates?

I have a lot of Lapua 6BR brass and a new Shark can in need of use.

I am looking for data for 220-240 gn bullets.

KURTZ, your linkie no werke. :grin: Anyone else have a pic to share?

I was also just on the SSK website and there is no mention of this whisper.

[HotLead]

Kurtz, there is no picture on your link (possibly due to the server change?)

Does anyone else have a picture to share?

Also I was just on the SSK website and there is no mention of the 302 Whisper. How new is this?

[kurtz]

So it looks like nobody has any actual hands on experience with it.

Looks like I might have to get a 300 instead...

[Hoser]

I just got off the phone with SSK. I asked JD about some 302 data/info.

That didnt go well.

I even asked about buying data, I was not looking for a free-bee.

Oh well.

At least now I know where to not spend any of my $$$.

So what's the difference...or was the wheel reinvented?

[Hoser]

From what I can tell through pics, its a 30BR throated long.

I explained to JD that I had the barrel, reamer and a throating reamer. I just wanted to get/buy some info.

He said "buy a complete gun from me and I will give you data."

[dksd39]

Yep- he can be a jerk like that. He is short sighted and thinks he is protecting his product. He should be helping others as it would increase his business. I have spent more money shooting my rifle than the price of the rifle. Who cares that I did not buy the gun from him he should still want me to spend money but guess not.

Sierra edition 5 has 30 BR load data. Why not use that as a starting point?

Its all supersonic data that only goes up to 200 gn bullets.

This should give you an idea of what to expect with subsonics in a case similar to the 30BR:

Sierra 220gr/ 2400 10.2gr/ Win primer
Sierra 220gr/ 5744 11gr/ Win primer
Sierra 220gr/ 4759 11gr/ Win primer
Sierra 220gr/ Trail Boss 8.0gr/ CCI 200 primer

With a 150gr hunting bullet, you should be able to get 2600fps or better with H4198 powder.
