I think what we are looking at with the .3325 section is what I dread as more chamber than brass. It really really is a nuisance with black powder rifles. I think the brass should be taking up that space for optimal cast bullet performance.Here is a photo of my "pound cast". The groove diameter is .3085". The case neck is .3345". The section between the case mouth and the rifling is .3325". I don't know what the correct name for this last section is. Is that the "throat"?
So with this information, what should be the diameter of the bands on this Accurate clone of Saeco #315 be when powder coating is going to add .002" to all the diameters?

I can handle being told I'm wrong though. But I would prefer .005" of clearance after the case mouth.
