....and so How's Your Luck Holding?

No fire rated safe helps over here.
The heat is so intense, fueled by Eucalyptus and pine trees.. the oils in the timber begin to create vapor and when it ignites, blows the door off the safe.(haven't you watched that video?)
Probably why powder containers have weak doors so they vent instead of exploding.

Over a certain amount of firearms, different storage is required, Phil's last was an external vault(maybe he should have put it underground) steel and cement...didn't help, the heat is just too great, once the timber started to burn..... The big problem is even if you could restock the firearms, the heat damage to the metal is an unknown, they'd never be original and you probably wouldn't like to fire them.
