With components in short supply I bought a large number of once fired nickel 38 SP cases from an online commercial vendor. Several cases were unable to be decapped. Most of the primer would be partially pushed out but a portion remained stuck in the case securing the whole primer to the case in a manner similar to a partially opened tin can lid. Forceably removing the primer by hand tool reveals a thin rim of the primer metal still stuck in the primer hole.
Most of the cases were OK but finally, sizing one of the difficult cases resulted in a bent decapping pin. I have close to a hundred cases left which I do not want to try and resize due to this problem.
I have never seen this before but I assume the cases are so old that it is corrosion that has seized the primer to the case. I am thinking of soaking these cases in Kroll oil for a few days and then in solvent to remove the oil; then trying one more time to decap them.
Any suggestions? Anyone see a safety issue with my soaking plan?
