We maybe did visit it earlier and I may have missed it. Sorry. Just seems like a lot to understand. I do understand that the barrel should be the deciding factor and not the case guage when determining a finished round and how it will function in a given Firearm. I guess in all the YouTube videos I've watched it shows everyone loading a bunch of rounds once all the dies have been adjusted and then they proceed to drop them all in the guage to see if they pass the plunk test. I think I need to watch someone in real time on the proper technique on what to do and what NOT to do.
