How much pressure can a rifle take?
This test is a look into what rifles will be torn apart by high pressures.
Witness this burst test and see if possibly your rifle survives the test.
Rifles as with all firearms operate within certain pressure parameters. If the pressures are too high, the weapon may have a catastrophic failure of epic proportions.
What is the best way to avoid this? Never hot load cartridges over manufactures specifications. Never fire a weapon with an obstruction in the barrel. Overall take care of that weapon and it will take care of you.
The rifles in this video shared by YouTuber ccc0mb0_bReakeR shows what happens when rifles are fired with obstructed barrels. Be careful out there, the life you save might be your own.
