I trickle every load that I weigh, using an RCBS powder trickler and a 5.0.5. scale, That's the one thing that I can't ever do differently, I can't bring myself to be satisfied with anything other than absolute perfect weight.
I know that everybodies scales will read differently, to an extent, but I use the very same scale and Uniflow since the late eighties, and I damn sure ain't screwing with it now,,,, And that unflow can throw some inconsistant weights, so I always set it up low and trickle to desired weight EVERY round.
