Can someone explain to me the process of going from 338rum to 257AM? or the like say 460wby to 338kahn? how many steps? do you neck turn before starting? neckturn when near desired cal? anneal during necking down?anneal just before loading or after firing? and finally when fireforming I would be inclined to use a false shoulder IE 6.5 on the 257AM but how stiff of a load do you use compared to a normal(formed) max load?
