The difference between a .224 and a .323 is almost the same. Except the frontal surface area is DOUBLE for the 8mm. All other things considered, the 8mm is running up against, resisting, and crushing double the surface area and tissue. Its not just a few hundredths of an inch, its a doubling of area. Its not just a double size wound cavity in theory, its more resistance and tearing.
The 45 is roughly 40% more area than the 9mm, meaning at least a larger cavity, and also more resistance and better damage in living tissue at similar penetration depths. Not a small difference at all.
