help with big mistake

[ww874]

I just spend several hours very carefully making up some ammo. I made the first batch with 4064 then put the can away. This is a one pound can and it's new and full.(I combined what was left of the previous can of 4064 into it so it's right up to the top. Then I took out a container of H4350 and filled my powder dispenser using the funnel. I then realized I had some 4064 left in my trickler so I took the can of 4064 out and took the funnel off my dispenser. Nothing fell out so I put the funnel into the can of 4064 and as i got ready to pour the remaining powder from my trickler into the can I realized there must have been a blockage in my funnel and it still had small amount of H4350 in it. As I took the funnel out of the can a small amount of H4350 dropped out into the can of 4064. Question is my new can of 4064 contaminated or is it still usable? I estimate no more than 25 grains (probably less) fell into the can.
