For what it's worth from my side of the vise. In short the Pre-64 is not an action to use for making a 416 Rigby. The action is to short, the bolt face does not have enough rim material at the 3 O clock position when opened up to control a round coming out of the magazine box nor is the std large ring 98 for that matter (its just enough for the std belted mag) The thread OD is fine for std belted mags but not for Rigby sized case no matter how you do it. I know it's been done before, even Winchester has tried some, that doesn't change the fact that it's a bad idea.
