I used to load a lot of .44 Mag with 300 grain Hunters Supply LBTs and enough W296 to kiss the base of the bullet, when seated in the crimping groove. When fired from a 4" Model 29-2, they could be counted upon to jump crimp unless the case mouth was buried in the bottom of that groove. Neck tension was not an issue; I had turned the expander button down 0.003 and there was plenty of neck tension. Inertia was the issue. In that application, it simply required more crimp to overcome it.
