I start using the RCBS 750 electronic scale and I noticed one thing. When loading for a 223Rem and I start at 24.5gr for a 50g NBT and do the first round and put in the case. I notice the sale starts to show - 0.1 before placing the pan back on the scale. Often when the next round or two is poured in the case it the sale will show -0.2 and I have seen this go to -0.3.

My question is since I want exactly 24.5gr and the scale shows -0.2 prior to placing the pan on the scale, to I weight up to 24.7 "to compensate for the -0.2"?

I know I read that these scales can be a bit finky with lighting and the like. But I make sure no bright light is shining on the sale etc.

What do you guys do that use a electronic sale and see these symptoms? Reason for asking this is when starting at the start level with the scale showing -0.02 will that bring my start a bit lower?
