I'm new to the forum and posted these questions in another thread where it did not belong. Subsequently I read the thread about the plunk test which I'd heard of but never seen explained so well.
I have reloaded about 1200 45 ACP - and 200-300 9mm and never used the plunk test, rather used an OAL (after testing some slightly longer and working my way down to OAL cited by others in a 1911 forum - memory serves 1.255. Diameter with taper crimp was set to same as factory FMJ and have had no lead shaving. I have not tested for pushback either.
Am I lucky to not have problems? Do I read the plunk test correctly to measure for an OAL and diameter that are flush or a hair below to maximize accuracy? My current OAL has fed and ejected from two different 1911's with no issues.
I also don't really know how to recognize leading. I've been told little balls around the rifling. My Dan Wesson barrel has had most of the 1000 rnds of LSWC shot through it and after cleaning there are a few gatherings of material - but not necessarily in the rifling (I'm fudging description because these old eyes needed more light and a magnifying glass - which I haven't used yet). I will tonight at home.
