Sorry for the quite late delay, but I did the "whole/hole" job myself. I have just a standard machinist drill set from #0-80, A-Z, and 1/16 - 1/2. That gets you close enough for just about...

That's why they call it a "Wildcat".
It's a non standardized round until someone gets it logged in with SAAMI and the commercial supplier ranks.

I don't know why a company would produce a brass that you can make from existing brass that is so cheap it is almost free.

I've loaded for some guns that did accept the 1.4 with no problems, but I have seen others that did not. I'm just wanting to see this thing set to a standard length.
It would be interesting to see...

300Whisper trim to length 1.355 not 1.400!

About once a month, someone is trimming down brass for their 300 whisper to 1.4". It's a pretty common mistake since that is the length of the .221 fireball; but not the 300 whisper. The real trim...

It's a pretty common mistake to trim 5.56 brass down to 1.4 since that is the length of the .221 fireball; but not the 300 whisper. The real trim to length for the 300 whisper is 1.355".
Don't feel...

Well, ok, but I wouldn't buy it if they did start making brass for the 300whisper. The military brass as well as .223 stuff is just too cheap to pass up for forming into whispers. I'm sure that's...

What we also need is more activity. I'm a little surprised at the lack of volume here. Nothing against your site in any way shape or form, I would have figured that the 300 would be more popular....

Nope,
I heat shrunk a SS sleeve around the pistol gas port and drilled another hole up at the front sight mount. I do have to offer a correction however. The barrel is not a 300whisper, but a...

I started out with .076" since I figured that it's always easier to make the hole bigger than smaller. After some loading development, I opened things up to .086". Everything cycles just fine at...

Using 223 brass makes the process much easier than the 221, not to mention a whole lot cheaper! I use a motorized case trimmer to cut the 223 down to 1.4". Next, deburr the case mouth. Lube and run...

The Speer 150gr. RNSP should expand just fine in the 300whisper. The bullet was made for low velocities in the 1,800fps area. My own pet load for this bullet is:
Winchester SR primer.

Not hard, just a different wildcat.
My best out of a 16" barrel AR15 with a:

Yup, they are the same round.
Mr. Jones from SSK copy wrote the name "300whisper" so in order to use that name on a set of dies, barrel or shells you need his permission, or more to the point, he...

Wrong:
The 300whisper trim to length is 1.355 and 1.365 max. Reference Sierra reloading manual. It's a common error to trim to 1.4 since that is the 221 fireball COL, but that's not what SSK set...

Greetings,
What is the gas port diameter on the 16" 300whisper?
I need to block off one and drill another.
Thanks in advance,
