Ah I get ya, do you mean dum-dum bullets? Although I know they're designed to fragment on impact.
But why would the true perpertrator's risk it, when the the sheer number of people in the hospitals that night, could easily dismantle not only those fake interviews, but the entire event? Why carry out a false flag terrorist attack, only to put actors on the news? Why not use the real injured people? Infact, why put people on the news in the first place? With all the mobile phone footage & social media stuff, injured people, whether they be real or fake, doesn't really add too much to the story.
Unless you're talking about media outlets faking the interviews, purely for ratings? That I could believe.
So over the space of about 10 years, I've used a wide variety of guns. From Glocks, to Magnums, to Sniper Rifles, to 12-gauge's. And I've always been fairly decent with them. The AR's I've used on multiple occasions are M16, M4, AK47, SCAR, and MP5, UZI sub-machines. I've tried all on full-auto, and granted its hard, but I've always hit the targets, and been ok with them. With one standard clip, holding the gun free-aim, I obviously couldn't hit the same small target repeatedly when on full-auto, but I'd certainly tag it 30%-40%- minimum. If I'd have used a bi/tri-pod, like Paddock did, I reckon I could get Upto 60%-70%
