At 700 rounds per minute you would shred them!
I use a .308 for dear at 1000 yards. ( also handy for other things) But my semi autos are for killing bad guys intent on killing me and my family. I have a constitutional right to do that . Otherwise, I would be out gunned, I also recommend 2000 lumin flash lights attached to the barrel. ( my shot gnns have those. Bad guys are blinded real bad and then are dead. Ban Wahhabis - not guns, idiots.
Name a semi-auto rifle that fires 700 rounds per minute. Semi-autos fire single shots. I tell the gun-ignorant that they're "single-shot" weapons because "single-shot" is more correct than "spray-fire".
