developing a sense for what is dipping in what when you move or take a position is also key.

AS mags are way more sensitive to crap than RS .. but even RS can and will foul if you jam a messy mag in.

I swap out mags from my dump every chance I get.. and I dump out the pouch and clear it whenever I am not engaged..

Lots of guys will stand around when they get a break .. and when the fight heats up again they will note that their mags are all fouled from the last time they went to ground.

I constantly check and re-check the status and condition of my ammo ... so I know when things are getting sandy and can take remedial action to ensure my ammo feeds when I need it to.

These kinds of behaviors have to become automatic habits that happen without thinking..
