Never had a rim failure, but a few split necks, yes.
Have noticed that the WW brand headspace varies some. This is only noticeable in my Martini with very snug headspace on Hornady ammo when I built the gun.
Never had a CCI or Hornady case display ANY headspace tightness.

The tight WW cases (not had one go off when chambering - that might be exciting) strike 3/8" to 1/2" to the right of the normal grouping, but also into a small group, when firing on targets.

I know, when chambering them, if to hold centre or to the left. Bit of a pain, but not insurmountable.
There is no change in the Marlin, firing the same ammo.
