My version: they tried to reduce parasitic mass of windshield compared to cone-shaped design. Such design affects less on axial fragment spray. Also spike design provides higher aerodinamic static stability margin compared to cone design, so you can make fins smaller or reduce fin count or move center of gravity to the base by adding base fuze, there are lot of factors. From penetration point of view all projectiles look same, they all have solid, ~1 caliber head if you remove windshield.

Basing on what principle users post materials in this thread? I have hundreeds of reports\theses\presentations about weapon design, most of them are from dtic. Here is list of aerodynamics folder:
