If you can keep 70% of your shots (using support) on a B-6(P) 50-yard slow fire target I think you could maybe pass the FBI qualification test.
My question is simply why do you want to work at 50 yards ? That distance ought give you room to 'exit stage left'. Again why do you want to engage at 50 yards ?
When the number of people in institutions reaches 51%, we change sides.
