If I'm on point I'll dump 6 75rd midcaps in less then 3 minutes on a large engagement.
^also assuming I dont die when the other team opens up. I do this not because I like to spray but because I literally am the base of fire until our heavy gun opens up. We also run a relatively small squad so being able to keep the same volume of fire as a larger force is very important.
If I'm running my basr I'll shoot maybe 40rds. Most of the time less.
I play with 3 PMAGs which hold 40 rounds each, for my G&P WOC SR-15 10.5" GBB, plus 1 magazine (25 rounds) for my KSC P226R.
I don't care if with electric spray and pray ninjas I get outgunned, the reason I play is to improve my actual fielding, maneuvering, trigger control and reaction to contact. I am definitely planning to add more mags soon, but I need money first
AEG's I guess around 1000 to 1500 per day (hicaps) but my team mates seem to go through 4k+ per day so I am quite conservative. That's quite high contact days.
Spent a morning with my VSR (afternoon was more speedball style) on a 4 hour roaming objective based game and I went though about 6 VSR mags so I guess thats about 120 odd? Got about 15 or so tags I guess? That's quite a lot of defending positions and having people repeatedly attack us though.
