Here is my two cents worth from my experience in the sand box. Tha army told us to fully load are m-16 mags which most soldiers did. Me and my soldiers only loaded to 27 or 28 rounds in our mags because i knew that if we fully loaded them they would jam on the first round or double feed which would be bad if we got in a fire fight with the bgs. We also put a tracer round every fifth or sixth round and three at the bottom so we knew when to put a new mag in. I know as civilians we wont use tracers in are ARs or whatever we shoot but i know from experience in the AR-15s and m-16s they will jam if the mag is too full. I keep my pistol mags full though and i am really glad for the information because i was going to ask about keeping my mags full all the time.

It was not because of the sand and grit although that does not help. I think it was becasue we had old guns and new magazines. The feed throats could have been worn or they just did not sit right in the magazine well. I never had a problem with mine when i had only 27 or 28 rounds in it.
