Scroll down to the pump rifle for some truly amazing footage. Wouldn't take this dude pig shooting; you'd never get a shot in

I was present at an Army/Civvy shoot a few years back when a grunt fired 30 rounds in fifteen seconds using the F88 on semi-auto. His bullets struck the ground every where between 20 and 400 yards with only two on the four foot target at 100 yards. On the other hand I've fired 30 in a minute at the pig target at 300 metres and hit it 21 times using the same rifle. Speed versus accuracy.
