I have not had that happen with factory ammo, but had leaking primers with 30 year old hand loads in a 300 WM. I pulled a bullet to see if the charge was OK, and it was.
However, I had much difficulty pulling the bullet, and found that the bullet and case were almost welded together due the carbon residue in the case mouth.

I set my seater die so that it would just move the bullet. When it did there was a pop, an indication of the "seal" being broken. End of problem.

Now when I use old handloads I always do the same and sometimes old ammo will pop.
If case necks are very clean the problem does not occur.

I doubt that is the problem with the old factory rounds, but have had high pressure, demonstrated by very difficult bolt lift, when firing OLD GI 30-06 ammo
