I consider this idea to be total insanity. The guy is lucky that he wasn't seriously injured.
However; the video contains good examples of what to look for concerning high pressure loads.
I think a better way to test this would have been to use a string to pull the trigger so I could be away from a possible gun blowing up. Personally I wouldn't ever try this.
I have heard of wad cutter bullets being turned around with supposedly no problems but that is different than a rifle pointed tip round.
That fact the rounds, blew back primers and split cases should be a hint you are living dangerously. It your rifle is not in the best condition or of quality you may be in for injury. I wouldn't subject my toys to that abuse.
Funny morons! I would like to see them try that same ignorance testing with a Glock. I have seen these num nuts doing other videos trying to show how a HighPoint is junk. I don't own a HP but I really think the same testing would show a Glock or any other gun would fail these tests.
To funny pounding a bolt into the barrel and wonder if the gun will fail. I am waiting to see a Glock comparison test from these funny guys.
The ONLY Correct Application for Seating a Jacketed BTSP Bullet Backwards is for Carefully Developed & Loaded SubSonic Rounds to be Used w/ a Suppressor.
There is a World of Info on This Available OnLine.
And, There Are Actually Manufacturers of This Type of Round.
However, Handload Info is a Little Difficult to Find, But, It Can be Found.
I Personally Have Done a Lot of This Type of Load Development for My .308WIN Bolt Rifle.
And, Yes it Works Great. Within a Specific Set of Limitations.
Not for High Power Loads or the Novice.
But, When Done Properly, Makes a .308 Sound Like a .22 Short!
Just a Lil Info from someone who's "Been There Done That".
