Explosive minigun and turning anything into hamburger

In FO4, if you can manage to find the legendary explosive minigun, it is definitely what a real minigun should be able to do in real life unlike the standard miniguns in the game - definitely the perfect gun to go Amityville Horror on anything in the game. Turns everything into hamburger if you have the one perk that causes people to explode as well. 😀😀😂😂

I was only able to find an explosive minigun after I was level 110 something and only on survival mode. My first playthrough on very hard, I never ever came across one. It’s like a holy grail find.
