I saw a fella shoot a 1200 nitro express(600 NE X 2 ) just recently
The rifle was a H&H Royal Double 600 NE.
The People close to him when he fired the salvo made sure the rifle never hit the ground,checked the rifle before they checked him.
I honestly believe he was still in a state of shock 30 minutes later..
He took at least 2 steps back on firing but still had both hands on the rifle when the dust had settled much to his credit.
I am sure no one wants to follow in his footsteps.
