Are you lubing the cases and cleaning them afterwords? Seen that happen to more than one person by not cleaning off the lube. If you are and they are sticky after resizing you have a very tight chamber or you dies aren't doing what they should, but since it's new brass sounds more like a dirty chamber to me.
