Well posted! It can be that familiarity breeds contempt, or at least complacency. I know in my case, I did much the same thing. I was reloading some .308 and I had about 18 rnds. completed when I noticed that I hadn't set the 1/10th. weight correctly. After calling myself 50 different kinds of dumbass, I pulled all the bullets, dumped the powder back into the container and started anew. I had thrown too little, not too heavy a charge, so they'd have fired off OK and exited the barrel, but it would have been a waste of time for accuracy. My brother, god bless him, gave me a digital scale which I calibrate before every reloading session, so now the balance beam scale is pretty much just kept as a back-up. I've been at this game a fair while and the same principles that governed my carpentry career should apply to reloading, slightly modified. Where we used to say, "measure twice, cut once", for reloading it should be check and double check. Don't reload if you're tired or distracted or hung-over. Precision requires a clear head, a good eye, and concentration.
