This should be done with a light, medium and heavy pellet.
This was probably a bit unfair.
It's the AMTA test that rifles being tested for AT have to pass.
I suspect that the only rifles subject to such a test are those submitted to the Birmingham Proof House. Rifles would not be tested to this during production.
