You drop empties. You catch partials. That's all there is to it.

When you are doing speed relaods(you've run your gun empty and need to get back in the fight) you drop the mag and get a new one in as quick as possible. When you are doing tactical reloads you are behind cover in a lull in the fight and have rounds still in the mag. These you catch and put in your pocket for later. Should it last long enough to have to worry about how many rounds you have left, you'll be glad you still have them.
