But they all can blow if allowed to stretch far enough; some have less case support than others, so can tolerate less stretch than others. The cone breech gives adequate support when everything is OK, though, and there have been few problems with it.
The problems with the Springfield had nothing to do directly with the breeching; the M1917 Enfield, much praised for its strength, and the pre-64 Model 70 Winchester both have a cone breech.
