Doug,
It is not so much that the modern plastic is what runs the pressure up, it is more that the case goes into the barrel(in 65mm chamber),creating a constriction for the shot to pass through. This causes the pressure to go up, and would also with 70mm paper shells.How much the pressure goes up is often debated, and there are many opinions on this subject.
