Glad you rekindled this BP (and also glad that you and your gun survived the experience). I saw this gem a few posts up from Sevens 2 years ago that I thought was worth repeating:
To sleep well at night, institute a process at your load bench that will give you piece of mind so you have confidence in your loads.
Thats a great creedo for reloading. I would add to that: "learn from the mistakes that others have made and use them as lessons to improve your own process whenever you can".
I love and respect this hobby far too much to stop trying to get better and safer at it every chance I get.
