New .204 Ruger, .300 Whisper, & .223 Rem Ammo from Black Hills
Black Hills has announced three new types of loaded ammunition for 2012. (This is all-new factory ammo, not commercial reloads.) The first caliber is the .204 Ruger. The new round uses the 32gr Hornady V-Max™ projectile that has proven to be one of the most accurate and effective bullets available for use on varmints.
125gr and 220gr (subsonic) Options in .300 Whisper
The second is the .300 Whisper. This cartridge is the brainchild of JD Jones of SSK and has been around a long time as a proven wildcat cartridge. This versatile 30-caliber cartridge is designed primarily for use in M4/M16/AR-15 family of rifles and allows for use of a wide weight range of projectiles. Initial Black Hills loads for this cartridge are a 125 grain load that essentially duplicates 7.62×39 ballistics, but with far superior accuracy, plus a 220 grain Sierra MatchKing at subsonic velocity.
New 69gr SMK load in .223 Rem for AR15s
For use in AR15s with 1:9″ twist barrels, Black Hills’s customers have asked Black Hills to provide factory ammo loaded Sierra’s highly accurate 69gr MatchKing. In response to customer demand, for 2012 Black Hills will be offering the 69gr SMK loaded to 5.56mm pressures and velocities in military specification brass. In this new ammo, Black Hills has utilized modern temperature-stable, flash-suppressed propellant.

Pretty sure the .300 Whisper is in it’s death throes since the introduction of the .300 AAC Blackout. J.D. Jones was too greedy and held on to his ctg for too long, stunting its growth. No such bad vices with the .300 black since it’s a bonafide SAAMI ctg now and Remington is cranking out the ammo. The .300 Black chamber has the added advantage of being able to digest .300 whisper ammo in an emergency. The .300 Black was also ingeniously designed to use cut off .223 bulk brass without neck turning the thick mid body .223 brass after it becomes the neck. Bye bye Whisper, The new kid on the block is gonna bury you.
EDITOR: Dead? Well dig a little deeper… The two rounds are very, very similar. Here is a discussion about the possibility/feasibility of shooting .300 Whisper ammo in a .300 AAC Blackout chamber.

Specs: “The 300 Whisper and 300 Blackout have small differences in their brass dimensions: Blackout is 0.004 larger in the neck, 0.018 longer case length and 0.16 longer OAL. Also the Whisper is a wildcat while the Blackout is SAAMI standardized.”
Since the AAC Blackout is very slightly bigger all around, I think you can figure it out… but of course no one will officially recommend you fire a Whisper in a Blackout chamber. John Hollister of AAC says: “300 AAC Blackout and 300 Whisper ™ are not the exact same thing. It is similar to .223 vs 5.56mm in that the difference is in the neck of the cartridge.”
I think I understand you said the .300 Blackout neck is made with simply shortened 233 brass and the forming a neck for .308 bullets leaves the neck the finished neck thickness. What source do you recommend for making and loading the Blackout?
They 300 Whisper and 300 BLK are the same thing one just has been standardized by SAMMI As a matter of fact you can shoot a 300 Whisper in a 300 BLK chamber, even Hornady states this on their website. The Dies are the exact same as well.

These rounds are for having fun blasting in semi or full auto. CQB, 3 gun,steel challenge games and such where high volume shooting is the norm. (Also some supressed bolt gun apps too.) Who wants to use expensive, hard to find in volume .221 fireball brass ? Who wants to cut .223 brass down and then have to neck turn it too? (we are talking 1,000 rounds at a time) Just seems to me to be a no brainer to pick a .300 Black chambered rifle or upper where you can run .223 brass into a dillon electric carbide form-size-cut off die and load “as is” and run it. I can’t imagine anyone wanting a whisper wildcat when you can run a thoroughbred SAAMI ctg in a high volume application. The whisper was an excellent idea in it’s time. . .new chamber designs like the .300 Black that think outside the box and think about reloaders and making their life easier are clearly a step above IMHO.
