Here's a belted fired case next to a non-belted fired case. Left is 450 Watts, right is 270 Win. The forward edge of the web shows but have to look closely- it is the interface between the shiny and scuffed surfaces. The white line points to the forward web edge on the belted case. Note that the forward web edge on the belted case is in nearly the identical location as the forward web edge on the non-belted. The issue is that the belt gets in the way of a conventional sizing die when trying to re-size that area when resistance to chambering is felt. The conventional die sizes right over that edge on a non-belted case. A conventional die WILL NOT size over that web edge on a belted case, even though the edge is in the same location in both non-belted and belted cases.
The best way to size that relatively small, specific area just forward of the belt is with a collet die. The cost of the tool has nothing to do with how it works nor it's effectiveness in dealing with that one specific sizing issue. Although that differentiation seems to get lost in the discussion of this subject. I too swallowed hard and just gritted my teeth when I purchased one a few years ago. But it has saved a bunch of waste of expensive brass and ensures trouble free feeding of the belted DG cartridges I shoot.
