Can you re-assemble your neck die with the de-capping pin/neck expander adjusted so that it doesn't de-prime?
Just run it in and out of the neck and it should be good to go. If you are worried about the 9 rounds that you have loaded up, just pull the bullets and do those as well.
I can't see any problems shooting those off as is, may just not shoot to the same point as "normal".
