The power is there to shoot bullets. Rarely considered is that part of the apeal of pellet guns is the crappy ballistic coeficient. The low bc means the downrange hazard beyond the intended target is minimal. “Improvements” to the carrying power of airgun projectiles could easily eliminate the virtues over pb guns.
My favorite gun will shoot 34 grn JSBs or 12 grn wadcutters. I focus carefully when using the 34s, I relax quite a bit more when using the 12s. The 12s will tumble or shatter at the first leaf or twig; the 34s have scary carrythrough.
From an engineering perspective, with maximum stopping power as the design objective, diabolo pellets are non-optimum. If the objective is redefined as effective stopping power applicable in a civilized environment, diabolos start to shine.
