ok thanks Bob, I'm calling the .010 groove it cuts crushing. Maybe not. I'm just use to loading straight wall where an overcrimp effects headspace and accuracy. I guess this is the reason they recommend an OAL of no more than 1.224( the crimp might effect accuracy if its in the middle of the bullet). Overall I guess I've been lucky not to have bullet setback with a 1/2-3/4 turn crimp depending on the hardness of the bullet. Like what you said in a post above, its probably better not to chase 10mm velocities. Maybe a fast 40sw with lower pressures should be the goal.
