Load data on 69/75gr TMK's?

[MarshallDodge]

I am using an RCBS and I easily get a +/- 0.1gr variance using it with XBR. Sometimes it is off by 0.2 or 0.3!

In order to get my target of <5 SDs I have to weigh every single charge to within 0.05gr. My process is to use the progressive to get me close, and then I use tweezers to pick up individual particles of XBR to either increase or decrease the charge weight to 23.48 ~ 23.52

There are too many other variables, including wind, to be picking up powder with tweezers.
