OK so i have used redding dies a lot and love them but I just starting using a 308 type S FL die and am having some issues. I am using a forster Coax press and im using the ti nitrided bushing. I can only get a little over half of the neck sized down. I cant figure out how to fix this and need help. grinding any of the bottom of the die off would just mean i am bumping the shoulder back more and I have the bushing stopper on top all the way down and just barely backed off to allow the bushing to move freely a little. any thoughts?
