Putting the objective close to the barrel isn't beneficial for that very condition, it is just the result of one trying to reduce scope height to obtain a cheek weld. I won't own a rifle without an adjustable cheek weld anymore. It really is that important to accuracy. So, the typical clearance of my scopes is 3/8" with scope Height Over Bore 1.7-2". No worries about scope cap clearance, scope flex, brass ejection. It is the easy button for scoped rifles.
