    Tom, I don't own any Redding Dies and I am curious as to what is wrong with the
    Redding expander and what you change yours to. I switched to buying Forester dies
    about 10 years ago and just haven't ponied up for a set of Reddings yet.

    Here is something from Redding on what they supply with the Type S die.


    A decapping pin retainer is also supplied with most Type S - Bushing Dies except 17 and 20 Cal. This enables neck sizing without the use of the size button for those who sort and/or turn case necks for uniform.

    The easy button for getting rid of the expander ball. Well,... it's never easy.
    Thanks Tom.

    Case head separations are especially common with belted magnum calibers. Factory loads headspace on the belt, but handloads MUST have -.002" or less chamber clearance at the shoulder.



    Picture from a good article on www.larrywillis.com
    This shows how case separation begins inside of the case. Reducing chamber clearance (at the shoulder) prevents the case from stretching (and thinning) the brass. Full length resizing is the way to go, but your die height MUST be set accurately, and measuring is required.
