Interesting article, thanks for posting.

The "god-like" comment is a self-promotion by Petzal?

My one "heathen" comment however: "...fits through a standard length action" is a bit of a stretch for the .416 Rem and the .404 Jeffery (pun intended!).
It takes some serious gunsmithing to open up the Mauser 98 size actions to accommodate those two cartridges.
These days, manufacturers make a standard 'magnum length' action for those chamberings.

The .416 Taylor, on the other hand, is a standard length 'forty'.....

...but nary a mention!
