i'm trying to find out what's required to use a longer cartridge in a long action receiver for 3.850" mags. from some understanding the bolt stop needs to be changed to accommodate for a 4"+ oal. does the port need to be opened up also? then there's the bottom medal and stock fitment for the change or just a chassis or stock that accepts said length(s). so far i'm just looking at bolt faces of .590" and maybe larger diameter wise in .640 or .810" range. not specific on which cartridge will be used for now?
