It’s wise not to mix different caliber ammo together.
This shooter did not heed the warning and paid the ultimate price.
Witness what happens when the wrong caliber gets in the wrong gun.
In a video shared on Facebook by Rogue Gunn Works we see how to explode a rifle in short order. Load the wrong caliber into it.
Firing a rifle in 5.56 this shooter had loaded a single 300 Blackout cartridge. When the round tried to chamber there was a serious kaboom. The rifle blew up and ended up a massive mess.
Luckily for the shooter and the bystanders no one appears to have been seriously injured. What was a total loss was this weapon. Do not try this at home!
