I've been doing some reloading for a friend. He bought a bunch of LC .223 brass and a set of dies. I have RCBS, Lyman, Redding and maybe one other type. Anyway the de-capping/F.L. size die is very moody. To little lube while on the up stroke and it feels like I'm going to pull the rim off the brass. To much lube and you guessed it, oil canning/dents in the shoulder. I've even put a little lube inside the case neck. That works great for about five shells. Then very hard once again. I've never had this small of a window on any other F.L size die. The only thing I can say good about this die set is the bullet seat die is amazing, it's smooth like KY with the neighbor girl. It's like the decapping pin should be lubed frequently and thats not normal at least with my other dies.
