The Sierra match king bullet (used in Federal GMM) has a hollow-tip, which is a by product of manufacturing and not intended for expansion at all. This hollow tip effects accuracy NOT AT ALL. The US Armed forces switched to the Sierra Matchking 175gr with the M118LR ammo, this was a switch from the 173 BTFMJ in the M118. But, like I said, it was not because it had a hollow tip (we are not allowed to use exanding bullets in combat anyway) its because its a superior bullet. Now, Lapua exceptional bullets also, but theirs are all FMJ... again, its all in the quality and design of the bullet.
Some people have argues the hollowtip has aerodynamic advantages, but I would argue more that is does NOT have aerodynamic DISadvantages.
