5500 fps from the 6.5 CBJ???  

No its an enlarged version of the cbj.

basically a grendel case wjich easily does 5500 wih 31 grain bullet. Im wonderig about things like noise and just being unpleasant to shoot.

Seeing buffmans recent vid of the tungsten 338 failing to penetrate,  im convinced that hyperspeed is a better approach

Damn I cannot embed them here

Lets see if this works:

thanks!

How did you embed it?

It's that little button (light blue above) next to images, which is for embed links.

You get the embed link from twitter, them copy it into that thing. First time I've ever used it but it works well. 

The Textron gun is quite gorgeous...
