I've had several cases cracked just like you described. All has been mil-sup, even my czech favorite. The last time was a couple of months ago while shooting my PSL.

If it is a deep gouge in the shoulder, or neck that is a likely sign of a burr in the chamber. Have a smith check it out. If it is needed then they will polish the burr out.

Old military brass may have a neck cracking problem because of lack of neck annealing.Steel cases may crack because they stretch less than brass.
