I did get a chance to turn the inked dummy rounds in the chamber with needle nose plyers, it didn't really tell me that much so - I decided to check on the crimp and it seemed to prove some good results. Although, based on the dimensions listed in SAMMI and CIP specs - it should not be close to contacting at the case mouth, but it is unless that crimp is done in a very narrow margin. Maybe I need a roll crimp, or to trim the case a hair back to trim length - they are all still well short of maximum. Another issue that's come up - is some of the bullets will wiggle and turn in the case after they are set and crimped. Not sure there is anything I can do about that other than find different tools and/or components … dies and bullets. I should put a caliper on the expander just to see what the dimension is, but the bullets if they end up loose are not being gripped strongly enough.
