@ OP, the idea of making a more aerodynamic "bb" has been around for a long time. Tiberius tried to do it with their paintball markers and created the First Strike round that was extremely expensive, marginally effective and was almost uniformly banned from all field as it posed a safety risk.
the type of ammo i'm talking about was before those caps gun ammo these look like conical mushrooms, made with very soft plastics and usually white or pink in colour, eventually they evolve to a more rounded form (like the current madbull nades but way smaller) for the classic MGC/Maruzen springer an back to the bb format we are familliar today
