Simple question, how many blasters do you own? And how massive is your store of magazines/clips/belts and ammunition?
I would hazard to estimate I own 31 blasters of various types, most being flywheel powered. I have one Rival blaster, a Khaos, and just the one Khaos magazine, and a store of around 100 HIR's. I do have numerous semi-and-full-auto blasters, including a JLCustomsCreations Rapidstrike and a Regulator as centrepieces of my arsenal.
I would estimate my .50-cal dart stores to be somewhere in the realm of 1,000 darts and I have 18 18-round magazines, 8 22-round magazines, one 35-round drum, one Magstrike clip, one modded 75-round Vulcan belt (no Vulcan though), an enforcer belt and an Enforcer, as well as probably 9 Demolisher rockets and about 60 Mega-caliber (.75 caliber) darts.
