"They just prevent damage falloff at the distance of 75-100m." AC42 HP ammo does indeed prevent damage dropoff at this range but that's not true for all guns. For instance, in the case of the AK24, high-power ammo extends range at which the rifle outputs max damage of 28 hp/bullet by 10 m and "medium" damage of 22 hp/bullet by 75 m. Source: sym.gg
HP does increase damage in some sense, just not the max damage. If you want increased damaged output at close range, you should try close combat ammo (only available for certain guns e.g. m5a3). increasing damage at close range for other guns would be a bad move imo
