UTG 727 destruction

Best of luck getting it to critical mass. Will a cracked drum explode, yes, because it is already compromised. A good one has to spin around 18-19K+ to hit critical mass. Not many street guys are getting there.

In all the years I've been around this stuff, the number of 904 drum explosions = 0

Can't say that for the 727.

Yep, the closest I have seen in person was a 904 sun gear shell flared out enough to start cutting the case in half from the inside.
Had not come through yet.
