RE: New Rambo
Just to add to what G2 is saying. I totally agree that the movies are just that movies. 1 grain is 1/7000th of a pound so a 650-750 grain bullet will make a huge mess of a person's head at any range, but being blown in the air for many feet.That is just for the movies. Also if it did blow people in the air when hit I really don't think that the biggest and most affective muzzle brake would be able to tame a rifle that would also be moving the shoot the equal amount in the air or along the ground.
