The same thing keeps happen. The mods on the dragon doesn't work at all. It should clearly be 40 bullets with the clipsize but nonetheless it is only 20 bullet, like without clipsize. Naughtydog needs to look into this
Max ammo icreases bullet count, clip size increases the clip size (go figure) to 7 instead of 5. Draza's dragon is equiped with CLIP SIZE (not max ammo) as well as call out. You're confused, this isn't a problem. It's all in your head man.
