G&A TV: .300 Blackout vs. .300 Whisper

by Guns & Ammo TV   |  April 21st, 2014 4

Rifles chambered for .300 cartridges are emerging from several major manufacturers in the firearms industry, and that’s no coincidence.

Originally developed and marketed by J.D. Jones, one of the main attractions offered from the .300 Whisper cartridge is the ability to choose between subsonic and supersonic loads for the use of suppressors. The .300 Whisper is also adaptable with standard AR-15 parts and magazines, less a larger diameter barrel and muzzle device.

But we’ve also become accustomed to the .300 Blackout cartridge from Advanced Armament Corp., which appears so similar to the .300 Whisper that it has many people wondering: What’s the difference between the .300 Whisper and .300 Blackout?

On this segment of Guns & Ammo TV on The Sportsman Channel, Sgm. Kyle Lamb (Ret.) and Craig Boddington discuss the similarities and differences of the .300 Blackout vs. .300 Whisper cartridges.

For more on the Blackout and Whisper, check out the May 2014 issue of G&A, where Sgm. Lamb (Ret.) goes deer hunting with a 110-grain supersonic load.

    “When i go to prison”…….lol……careful there.
    I’m glad you two didn’t utter “what difference does it make”…….
    Kudos to Hornady keeping JD Jones’ Whisper alive……JDJ broke ground on those cartridges. I recall him having worked with Jurras (sp?) on the Super Vel line of ammo.

    If I it is no good for hunting, I don’t want it around so some prosecutor can call me a assassin in waiting if I have to shoot. The “when I go to prison thing” reinforces my viewpoint. Just saying..

      That’s a cop out comment – You have the right to defend yourself and your family and you better defend that right

    The .300 Whisper is a fine deer cartridge. I have taken several deer with it over the years. (I used tol ive in a shotgun, single shot pistol/revolver state with a straight wall case or bottle neck case length of 1.4 inches Max.) Never had a deer take more than one or two steps with the Nosler125’s at out to 150 yards. Shoots sub minute of angle out to 200 yards out of T/C.
