Displayed Ammo Address

Is there an address that is used to display your ammo? I don't want to freeze or alter it, I just want to be able to read how much ammo the user has left and have it be displayed in a trainer. I have been looking forever for an address that displays the ammo on the users screen, but I'm just not having any luck. I even tried looking for some kind of pointer towards the dynamic addresses that you can use to freeze your ammo. I figured i could then read the address that shows which gun you have out then use that to figure the user's ammo. Anyone have any ideas please post.

you could also figure out the algorithim used to calculate the values for the guns...if you help me collect some addresses i might be able to figure it out

its k2 lol...i doubt it will take more than high school math to find a pattern
