[QUOTE="Ridge Runner, post: 87358, member: 951"] 180, according to a ballistic tech at sierra, flattening of fed 215's is nothing to be alarmed about unless it is present with case head expansion. Seems the fed primers have a very soft cup. as for your fl resizing try setting the die to match your chamber. Here's how I do it on my dies run a 7 rum case into a 30 cal die or use a 30 cal expander ball on your 7 rum die. once you have a case that is 30 cal, start with your die screwed way up, run the case in the die and try it in your rifle each time, screwing the die down a bit after each time, when the case fits the chamber and you feel lightest resistamce lowering the bolt then screw the die down 1/4 turn and set the lock ring and tighten the set screw. your cases should exactly fit your chamber. hope this helps JS [/QUOTE]
