>>19957953>>19957956Sure, but that's comparing apples to oranges. Shrapnel was hardly ever a standardised weapon. What length and width type of sharpnel killed the most? What average terminal velocity does the most lethal type of shrapnel have?
See?
If you had to name 1 exact distinctive cartridge, on the other hand, that had the highest kill count, it would easily be .303 Brit. If you want to step away from small arms in general, the spear shits on everything anyway. And then what about arrows? They were the artillery of choice for 99.99% of human history. But then you have to remember that back then wars were small scale skirmishes and only a tiny fraction of today's population lived at any given time. While .303 was used in all these massive scale wars (WW1, WW2, British Raj) hitherto unparalleled. It requires a nuanced, informed approach to discuss these matters.
