Hello, When I first got my Tokyo Marui Hi Capa it seemed to run out of duster gas after 55 shots so I usually recharge after 50. Today I thought I'd check again to see how many I get and I got 100 with the last 2 being a bit weak. Does this sound right? I read someone posted they also get around 55. Couldn't believe it. That's a lot for 1 fill.
