There was a Jason Statham movie, The Mechanic, I think that had some ‘cool guy target practice in the woods moment’ and they were blasting off rounds and did a cool slo-mo so you could clearly see that they were firing crimped blanks. I’m sure next to no one noticed.
Even less so in Dear John when Channing Tatum’s M4 turns into an M249 so you can see the links of the belt flying out when he shoots at someone.
Point being, don’t leave town to dodge safety regulations and be surprised when unsafety happens.
