In fairness, I did once play a game where I had 9 mags (2 hicaps).
It was a learning curve as I very quickly realised I only used about 4 of them.
I only use 100 round mid-caps and even though it happens every single game I'm always surprised how I use less than 2 per game. If its a really heavy fighting game i might break into a third but not finish it and its very rare
its not a huge tank though, I dont get why people have whole patrol bags on their back, 8 mags on the front, 6 on the side, drop leg, thigh rig, and bolt croppers!! Even seen a guy with a telescopic ladder on his back once WTF!!
Where are you playing?
I was often worried about feeling things through equipment but i find hard shell stuff like mags or helmets - if they are up against your body then you feel the impact quite easily, plus quite a loud unmistakable sound
