Is the C.O.L. listed usually the distance between the ogive (sp?) and the base of the brass? What about when they list the minimum overall length? What do you do if you don't see a developed load for the combination of bullet/powder you are using? What I mean is I am loading a 30.06 cartridge with the Remington Core-lokts and Nosler BT. Each bullet is different and therefore would have different seating requirements based on where the seating die touches the bullet. I just don't want to get too deep on the bullet and increase the pressure too much. Is this a valid concern? I guess I could buy a different reloading manual for each manufacturer, but that seems kind of ridiculous. Can someone share the proper procedure for determining minimum seating depth?
