Right ...
In my very early days of reloading in the 90s, in a rush to get to the range, I rushed and mixed up the load data with another powder.
First round at the range went BOOM instead of bang and after checking to see if I needed to change my underwear, I slowly lowered the pistol and hands from above my head and quietly packed up my stuff as I realized what I had done.
I pulled the rest of rounds and ever since, have double and triple checked my load data for the powder I am using. And only one powder container on the bench at the time and powder in the hopper returns to the container at the end of the reloading session.
Did I ever tell you about my squib rounds?
I mean, how can I produce a squib round when I am reloading on a progressive press? Really.
Now, I have an inspection mirror looking into the case with light source to be sure I have the proper powder charge before seating a bullet.
And "one time" I copied/pasted the wrong load data and boy did I get a grilling from THR elders ... If you are going to copy/paste load data, do it right and make sure you always link to the source or don't do it at all. So I started screen capturing published load data ... And you know what? ... Grumble, grumble ...
I guess you can't please everyone.
So I am back to copy/paste but now triple/quadruple checking while leaving the copy selection highlighted on source page to be sure I am on the right bullet/weight/powder.
I guess I am just a mere human ... There must've been a product recall that I missed from my maker ...
