Not working small ammo is 1 mag,large should be 2,its not
No Large ammo bag provides +100% ammo, so one more mag, thus only one more bag in the case of LAD as this weapon only has one mag by default.
Are we playing the same game??? He even got 4 mor o liked
The large ammo bag does exactly what it tell you it does.
The small ammo bag gives you +10% ammo or 1 mag whatever is greater. So 150 rounds x 1.1 is 165 which is less than 150 +1 mag (300) so it is the + 1 mag condition applied.
The large ammo pouch gives you 100% ammo or 1 mag which in this case still only 150 rounds but with both conditions as 150 +150 is equal to 150 x 2 which results in 300 rounds.
So regardless which condition you follow you only end up with 2 full magazins in total AKA 300 rounds.
If you bring an engineer with you, you can have quasi unlimited ammunition belts for the LAD.
