Home Forums Reloading Big Game Rifles FLS die leaving ring at bottom of case?

I've screwed a bunch of dies down to the shell holder and its never scraped off a ring. Either the die is to small at the base or your chamber is large at the base is the only time ive had it happen.
Check to make sure there's a smooth chamfer at the very bottom of your die. Measure a fired case then one thats resized at the base if its more than .004 difference theres your problem.
