Over doing the neck sizing....

[Gamerancher]

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".

Once fired brass no problem fire forming them back to size
Just think about fire forming cases for improved chambers and how much stress that puts on brass
