Uberti changed to a deep dished ladle quite some time back, due to all the breakage. I think the VTI heavy duty and the track of the wolf and the current Uberti all look about the same. Whether one is heavier gauge I don't know. The current Uberti ones are much better than their previous flatter ones, for the reason Tascosa Joe said, but can still fail. I think more likely to fail with smaller calibers since less of the rim of the cartridge is supported by the front edge of the gate.
