wait! what about the dangerous pressure levels generated by the supersonic ammo oh the humanity....

So are they are going to chamber in black out or whisper or both? Or do they mean fireball since JD isnot chambering them?

[rsilvers]

I am not sure why they are marketing it as both.

That would be like marking a rifle as 22-250 / 22 Varminter. It just leads to the confusion that has plauged the 6.8 world.

Endless people are going to call them to find out which chamber it has.

[Spook]

What if they copied your chamber and are calling it a Whisper (R)? OMG is nothing sacred?

[Mike Bell]

Smith & Wesson's 300 is only different in that it's chambered in 300 Whisper, a wildcat cartridge that the 300 BLK is remarkably similar to; it is only shorter in overall length, which means that 300 BLK can be safely and accurately fired in a gun chambered in 300 Whisper, which is ballistically identical but a little more expensive

It is safer to fire Whisper(R) in a BLK chamber than BLK in a Whisper chamber - depending on which Whisper chamber it is. There are at least two and maybe four.

Why on earth would a manufacturer like S&W bother to say it was a Whisper chamber when it wasnt?

I know I'm not a rocket scientist , but I dont see the upside of lying to current or future clientele particularly when it can be verified.

I wonder if they will come out with 264 LB or the 6.5 Grendel next.

There are plenty of long-throated 308 chambers, and the rifle makers are not lying by saying they are 308 rifles.
