I have an Open can of BludDot powder, I opened it 2 weeks ago, used 25cc of powder, Thats about 6720/7000gr left. so I would say 96% +/- 1% left. It was opened for 30min, then closed up, and put away. The sales man talked me into it, and its the wrong powder for my cal. I would like to trade FTF for Power Pistol. I have no use for Bluedot anymore. PM me with your offer, thanks!!!
