Thanks for the replies! Yeah, I was thinking the micrometer would make it easier for me to get the seating depth set where I want it, but then remembered basically that with the smaller box, my options will be limited to the point that I won't need the micrometer anyway. So I'll probably just get a regular seater from Redding or maybe Forster depending.
So really down to the sizer. I am trying to protect the life of the case, and much I have read suggests avoiding pulling the expander through the neck is a really good thing to limit stretching, but bushing dies are not available from what I can find, for the 375. Maybe just have to live with the stretching, but with the cost of brass, I sure would like to make it last as long as possible.
It seems maybe a lee collet die for sizing, followed by a body die or a bushing die with the stem and bushing left out might be good, but can't find that right now...
