I have a problem with belted cartridges, but not with the original ones, like the .300 and 375 H&H, nor the straight cased ones, like the .458 Winchester Magnum and the .458 Lott. The H&H cases don't have enough shoulder to headspace reliably, and the straight cases have no shoulder at all, and must use the belt (which is really a modified rim) for that purpose.

; In actual fact, both the Super .300 and the .375H&H have enough shoulder for maintaining proper headspace.
: Belts today vary in headspace measurement to over .020", which is no 'maintanance' at all. Short case life is guaranteed when one reloads and uses the belt for headspacing, rather than the shoulders. Of course, straight cases need the belt but headspace with it (today) is sloppy. The bottle necked cases don't need the belt. Even the old .400 Whelen had enough shoulder to maintain proper headspace, just not enough of the people who tried to load for one, had enough knowledge to do the job properly. Ignorance creates problems where knowledge eliminates it.
