i just opened a can of H4350 tonight and discovered that rust had formed inside the canister. It was not the original can but an old dupont can that was reused to hold a different powder. What do you think should i just fertilize the lawn with it or risk it and load some rounds up to see if the powder is okay??? I am kinda hesitant on using it and think that spending the forty bucks to replace it is cheaper insurance in the long run. Any thought on this or anyone experience the same
