Scott is lucky to be alive watching that video really hit home for me, be safe and don’t be jacking around with handloads or surplus ammo that your not 100% sure on.

How to develop a flinch with one round.......

I have never seen that gun design before, but it looks suspect to me, as I have seen lots of threads in different applications pull like that over the years. I wonder if a heavy lugged bolt gun would have done that? I don't think I have ever seen a quality bolt gun rip the lugs off of the bolt, usually they tend to split barrels when they have way over pressure rounds, but maybe they have

Have any of y'all shot one of those 50s, or have any other insight?

Glad that dude is OK, looked bad

The variation between the different rounds leads me to believe these were someone's home-rolled SLAP rounds rather than actual surplus. The fact that the endcap threads sheared tells me that something was very wrong with that round, enough to overcome whatever safety factor Serbu engineered into that gun (a lot, I'm sure). And the fact it made a 20lb gun go flying just shows the power when you detonate 750gr of questionable powder at once.

I don't know if another gun would have fared better- would the side of a Barret receiver flared out and sliced across his face and neck? We can't say for sure, but I can definitely say that one shouldn't be shooting SLAP rounds of questionable origin out of anything.

Very lucky to still be alive!

What was the thing that flew forward when he closed the gun at 3:17? It flew forward and bounced off the table as he closed the action.

Pretty sure that was the last of his 'good luck' or maybe his Guardian Angel throwing in the towel.....?

Having in advance a solid and legitimate answer to "Why were you trying to..." is a good, common sense safety guide for just about anything. And everything you can offer about what caused an accident to happen does nothing to answer that question.

That whole gun and it's breech locking mechanism just trips me out. I'd feel iffy using a screwed on cap system for a rimfire let alone a 50 cal. Just seems like a poor design.

We put a surprising about of trust in threads every time we use a modern firearm. Most have a barrel screwed into the receiver or action.

Mark Serbu has posted on a couple forums about the amount of thread engagement being like 1.75 square inches. That's a lot of metal to shear. Could be metal fatigue from the previous rounds.

I'm pretty sure a butterfly isn't designed into an RN-50. You can see it fly between the chair and his back the split second before 3:17

That guy is lucky to be standing there making that video. I'd be shocked if this was anything other than an ammunition issue. That gun has been on the market for years. If this was a design/quality issue, I think it would have presented itself well before now. I hope this is a wake-up call or reminder to folks who load their own ammo on the importance of attention to detail, and a warning to people considering buying homemade ammo from less-than-reputable sources

I watched a video that has an educated guess, but SLAP rounds aren't meant to be fired from rifles with muzzle brakes or any type of muzzle device.

I've heard this from several people and this one makes more sense than other theory's. When watching the video even he commented on the muzzle flash getting more intense. The fact that it was starting to sling rounds makes it more believable. Basically it sounds like the sabot doing what sabot's do which is separate from the projectile, were separating in the muzzle brake causing an obstruction. Where I disagree with this video is his comments comparing a bolt to a threaded cap. I don't see the cap as being weaker than the bolt. While it looks like something from Sanford and Son it's a very strong design that's been in use for many years. I've seen a couple of bolt rifles shear lugs and read instances of many more, AR-15's suffered lug shear surprisingly often at one time. The two i seen was a Winchester 264 and a Mauser action in 30-06. And yes there were reports of some folks eating a blown out bolt.
