The HUD has a display limit of 255 for bpammo (I think) and 127 for clip ammo, memory holder is bigger than that.
And I don't really know how ham gives ammo but if it just "gives" player the ammo and doesn't forcely sets the ammo, it will limited to 35...
But why don't you just test it, what's the problem ?
On "think", I can't really tell you anything certain there.
