what are the advatages / disadvantages of loads gaining their muzzle energy largely from heavier bullets as compared to those more relying on velocity?
E.g. some 5,7 loads may have the same ME as some .45 acp ones, still of course they have completely different properties in terms of inner, outer and terminal ballistics (are these the proper English terms, by the way?)...
I have already elaborated the differences in terms of outer ballistics: A lighter, faster bullet will have a rather flat trajectory, but is much easier disturbed by anything it hits on its flight path. A heavier, slower bullet is as such limited in its range because of the quickly increasing drop, but within its range it's less prone to deflection. Did I get that straight?
So what about inner ballistics (felt recoil, required barrel lenght, muzzle flash) and terminal ballistics (penetration, energy transfer etc.?)
