Proof has a chart online with a drawing of each of the contours offered. They give a dimension to the shank. The ones I've used (dozens this year alone) can sometimes be massaged into another action depending on the length of the shank or find an action with 1" x 16 tpi threads and see if just adjusting the headspace can be made to work. Older Winchester M70 actions, Post-64, have 1" x 16 tpi threads.
