Because if you use a FMJ, the base is open. Open bases are notoriously inconsistent and that degrades accuracy. Even Lapua discontinued their FMJ match bullets.
They are HP because everyone wants the utmost in length consistency for seating at the most accurate OAL. Soft points have inconsistent lengths and the tips are easily damaged.
Yes, the empty space/balance in the jacket has an effect on accuracy, however small, with Berger introducing their "column target bullets" that is supposed to have that empty space optimized.
