Pumped it up to about 40psi (26x2" mtb tire), and about a minute after I inflated and while I was reinstalling it on the bike, it blew out in spectacular fashion. So loud it sounded like a gunshot, and just a foot away from my ear. I still have a bit of ringing several hours later.

Damn tube burst at the seam for no reason. It was on the other side of the tube from where I patched it.
Maybe you pincehed the tube between rim and tire bead?
I've had similar thing happen to me once too. That time my rim had split open on the side, along the braking surface, due to being badly worn out, and the tube punctured on the new found sharp edge.
