I ordered some 250gr soft points from Hawk bullets for my Marlin Levergun but forgot to ask for a cannelure. I thought, what the heck, I'll just crimp the juice out of them with my Lee factory crimp. It didn't work. At the first shot, the stack in the tube all buried the bullets in the case as deep as the powder level would allow. I melted the other 49 down in the lead pot and threw away the jackets.
