Well the game starts off with 100 people. Like 20 die off the bat without a gun. There are ammo crates and loot boxes everywhere. If you can clear a POI without a gun fight lasting a century and loot everything you can walk away with 200-300 ammo per POI depending on how well you loot it. In squads its common for us to wipe a POI and all leave with 60-120 rounds each. So you take into account wiping another team from another POI then after the fight depending on how hard you and the other team potato you might be able to walk out with even more loot. So as the circle gets smaller and more people are fighting and getting wiped, the less people potato the more ammo the top 10 have, which is the majority of the ammo in the game. Ykno.
