I'm putting this out there for everyone else's sake. Luckily I caught my error before it could have been overlooked or possibly harmed me. I preach and harp to everyone that I teach how to load just how important paying attention is, but it can and does happen to the best of us. There is no place for complacency on the loading bench.
I was loading up some .260 after a day at the range working on some load development (140 grain Sierra Gamekings, 42-45 grain increments of Reloader 19, a new powder to me). I had decided that I was getting the best results with the 45 grain charge. I proceeded to load up thirty rounds. All was going good until I got to my last round. I verified my charge on a scale, lo and behold it was at 35 grains. This is the normal charge I use with Varget and 140 grain projectiles, but I had to get Reloader 19 due to shortages. I had inadvertently set up my powder dispenser for my usual Varget charge and overlooked it until I took another look at my load development data. This charge is 6 grains under Alliant's starting load (45.5 grain max reduced by 10%). Looking at a burn rate chart, Re-19 is much slower than Varget, and my research has turned up reducing slow powders is usually frowned upon past a certain point. I may still be in the safe margin with these, but just think what would happen if I had grabbed a vastly different powder, like 2400...
Just some food for thought for everyone else. Luckily I didn't learn the hard way, and I'm hoping this will make others take the time to double and triple-check before loading.
