As for the "get a Barrett" comments. People who can afford a Barrett are not generally buying an RN50, and people who buy an RN50 usually can't afford a Barrett. So, that advice just translates to "you're too poor to own a 50" for most of them.
Three lessons here ;
Always wear eye protection.
Never shoot questionable Ammunition.
Budget and 50BMG don't belong in the same sentence.
Having been around, shooting and testing 50Bmg rifles and ammunition most of my life, I have seen my fair share of failures and malfunctions.
Luckily most of the F&M's have caused more injury to egos + firearms, than life.
As was seen in the latest video and noticed by the trained eye, the Slap rounds that were being fired are/were fakes.
If they don't have any of the rounds left, or they weren't able to acquire more from the seller before the incident was publicized, we are only making educated/uneducated guesses as to the actual cause of the detonation.
Thankfully no one died and it was recorded.
That dude had someone else but his father watching over him that day.
