Since the .300WM headspaces on the belt, how exactly does the headspace get to be excessive?
That's the "official" headspace setter for belted mags. But for handloaders the clearance in the shoulder area is quite important, just as in other bottle necked cartridges.
BTW, I'm not arguing pro-OP.
I understand that. However, since the belt is there, the shoulder spacing is largely irrelevant so long as it does not shrink the length of the neck to an unusable length.
