So... I'm feeling a bit humbled this morning... Went and had a look at my scale and to find out when set to 0 with pan in place scale read .7 grains! I didn't re level the scale from the last time I packed up and moved I guess!!!
I'm off now with my head hung low to purchase a set of check weights and then pull and verify a bunch of rounds I have ready!
Thanks Renee for stating the obvious!!
