60 BMG or 70 BMG
Just wondering if anyone has wildcatted the 50 BMG to a larger caliber?

There are a few out there. They don't really make much sense rationally; they definitely fall into the labor of love category.

700 Hubel

And in today's political climate there could be destructive device ATF problems with using BMG donor brass.

I believe Robgunbuilder has worked up a couple monsters on the BMG case. PM him for details.

Huh, I didn't realize the Hubble Exress was based of the 50bmg. cool. I figured it may be an impracticable way to go about a big bore.

The USAF had .60cal based on the .50bmg case. Forgot what year, but I found some cases in ".60bmg" at an air base (in the late 60's/early 70's). An eod guy told me that they were .60 and not .50 cal. So I guess that a .60bmg would not really be a wildcat. not trying to stir the pot but I have held (and still have somewhere ) a .60bmg case. thanks lost

sskindustries has the 14.5mm jdj which is a 585 bmg. shoots a 1147gr bullet at 2700fps
can be built on any 50 bmg action.

Yep, On bmg brass I have three 700HEs... A 3.25" one,
a 3.87" one. and a 4.27" one.
Last gets 1000gr to 3400.

I also have experimental one, 4.3" long from a Hispano-Suiza
20mm case that'll do 1000 gr to 3800 or more.Ed
