When chamber are chamfered to not shave lead it isn't as easy as it sounds. There has to be two chamfers cut to not shave lead or one "way too wide and deep" of a chamfer.
When there's one chamfer then there is an edge deeper in that shaves lead so then that lower edge then needs chamfered. Makes more of a funnel to the opening. Makes for having to seat the balls a little deeper and loose powder capacity.
The plungers concave edge is there to push lead against the chamber walls anyway so shaving a ring isn't a bad thing.
Most of the chambers are a little tapered anyway in the Italian guns.
The best thing to do is ream the chambers to ,at least. be the same diameter as the barrels groove diameter. Makes for more consistant accuracy.
