"Bump" Die problems

We need more information to help you.

1. The type of brass that you are using.
2. Info on the kind of bullet.
3. Type of rifle, bolt or semi.

My guess is that your brass necks have gotten thicker from repeated firings and you have a choice of either "outside neck turning" or get new brass.
Check this video

Take your calipers and measure a case neck thickness in 4 places so that you get an average neck case thickness.

(average neck thickness x 2) + bullet diameter = case neck diameter

You may be able to chamber the round, but after it's fired it has too little space to expand and gets stuck.
