Anti-materiel is it’s primary purpose. For that 14.5mm beats the .338. The pictured weapons are for penetrating engine blocks that are stationary or moving with simple motion, within a greater effective range, not body armour (but will all the same). Long range extreme precision is secondary but is still a feature of 50cal and 14.5mm (top 3 records sniper kills are with a 50cal/14.5mm: #3 is actually with one of those type rifles).
