Case annealing sites recommend both 650* & 700* tempilac as a temp. indicator for neck/ shoulder area. Which do you use? Why? Also, do you use 475* tempilac on base of case to insure not overheating base. ............ Trying to establish time & temp standards for various cartridges. I use a variable speed drill w/ Hornady case holder (heat sync) & bernzomatic permanently supported w/ 1.25 inch to 1.50 inch cone w/ cone tip touching mid shoulder..... What techniques have been successful for you & this method? All input appreciated. Thanks, Dale
