Mhm. Cheat Engine works for this. I've tried it. Basic edits. Search full clip of ammo, shoot 3 times, search again, shoot 3 times, until it triangulates to 2 values, select both, edit them to max clip, done. Full clip. Don't attempt doing this while using fully-auto or it will bug the hell out. Honestly, fully auto is horrid anyways. I prefer semi.
