I recall reading somewhere years ago that during WWII, BAR gunners preferred M2 AP .30-06 over standard ball ammo. Is that true, and if so, why? Was it because AP performed better at chewing up cover in an automatic rifle role? Better accuracy? Or (and this was my guess at the time) was it out of convenience/availability?As in to my understanding .30-06 M1 ball was packed either in preloaded clips for Garands or belts for the 1919, but AP was in 20-round boxes.
