[QUOTE="boomtube, post: 599799, member: 9215"] Why do things vary? They just do, due to too many variables to write in a web post. A handloader learns to deal with variations as he finds them, reloading is not a 'one adjustment fits all' thing. Your present 'dime gap' sizer adjustment only insures the shoulders won't be sized correctly. FL sizing ajusts all dimensions of a case if it's done correctly. I suspect you've read about 'partial" FL sizing without understanding what it means; if we jam a case as far into a sizer as we possibly can we can set the shoulders further back than is neccessary and that produces unneeded case stretching during firing. The ideal is to set the sizer so the shoulder gets moved back to the fired location and no more, that provides ammo that will chamber but not stretch when fired. The grip on a bullet is determined by the diameter of the expander ball and hardness of the neck brass. There is no simple way to adjust for it but, if it's so bad you can pull bullets by hand, you may need a smaller expander. Hard brass springs back more after expanding than soft brass. Federal tends to be a little softer than others and that means it will last longer before splitting but it's a trade off for other things. [/QUOTE]
