new whisper ammo from Hornady
 

Just picked up a box of Hornady .300 Whisper I had the local shop order for me. ( Still waiting on some Remington BLK ammo) Im going to be checking out everything and compairing them to .300 Blk and the other .300 WTF ammo and my own 30/221 ammo. I'm just intrested in seeing and feelingin my hand the actual differences of all them.

:confused:Whats up with Wilson and his 7.62x40? Why would you go through all the BS when ACC and Remington basicly standized the Whisper? :confused:

Case capacity, better burn, better velocity with lighter pills, these are the reasons for the 7.62 covert also. When you can easily reach 2600 with a 147 it makes a diffrence.


Fyi, JDJones standardized the whisper everyone else copied and changed it, some "for the worse"

:bangin: OK maybe standardized was the wrong word :bangin:

But untill this year, all I could order was them high dollar Cor-Bons... I'm kind of glad ACC/Remington SAAMI'ed it.

A couple other companys had ammo available but was hard to get/find, thats why I will reload and always will.

Please post the official standard Whisper(R) chamber and ammo drawing.

Call 740-264-0176 , they can give it to you. :rolleyes:

The trim length should be more like 1.355 not 1.400 on the Whisper I do believe. Everything else looks right.

Remember cartridge drawings are 'max.'

The 1.368 brass length has a -0.020 tolerance.

So the brass is really anywhere form 1.348 to 1.368, or 1.358 average.

Rem brass that I have measured was 1.359.

this Hornady Whisper brass looks almost the same as the BLK. The brass length measures 1.359 also. And theneck length seems to be about .265 to the radious.

Would Hornady make their Whisper brass to the same specs as the BLK?

Yes, they had the 300 AAC BLACKOUT SAAMI specs and made the brass to be within spec.
