"Crimped blanks" can sometimes be dangerous themselves if fired at close range. The crimped part of the casing can sometimes break off and fly downrange causing injury if it hits someone. The report says the man suffered a "deep graze". That's not very specific, but sounds to me like something a blank round could do. I have seen people injured by blank rounds in person, although they were shotgun blanks and they were struck by the wadding. One of my friends got 5 stitches on the right butt cheek from a shotgun wadding.
yep;
We used to cut firewood during winter training , firing 7.62mm MG blanks from close range in tree branches , the pressure effect blasts wood in toothpicks pieces; I don't know how are made here, i found this photos, this is exactly how our blanks were looking back in "80s; I seen many empty with missing top, sure can cause injuries; `
The 14.5 mm blank was made diferent ,maybe safer, has some pressed paper cork on top, but the blast was more powerful, makes 10-15 ft. flame , and most steel cartridges cracked after firing;
