Until rifling was invented the range of arty was severly limited (range and probability to hit)
cannon balls are useful against fortifications (siege arty - heavy and large) and ships. Grape/case shot was employed only at short range (immediately before boarding). From the mid 18th century arty making became better and when cartridges allowed explosive ammo (19th century) arty became viable as long range anti personell weapons.
I think that's pushing artillery too LATE. Napoleon's guns were all smoothbore firing round shot - because round shot IS useful against formed troops.
