I wanted to clarify something I said in my B14 comments about the Clay core and upper inner core both being drilled in a one step process. This ONLY applied to the original B16/B3/b14 motors that had the .406 ID casing; when Estes changed the casing from .406 to .500" ID, they also changed the nozzle shape; the B14 that were created at this point and later used a formed clay nozzle core with only the upper inner core actually being drilled.
