Well.... actually in fact the longer length was not needed with a shorter bullet in the
30-03.....so 63 mm was determined to be sufficient length FOR the lighter bullet. shocked

THEN the 30-06 was designed w/the 63mm length case IN 1906.
It was MORE the bullet size/length that determined the length of the case THAN
the space need for the powder shocked
