I use (and am a fan) of my LNL AP press... and am also mindful of its limitation to charge precisely especially with stick powders.
Not just with progressives, any powder dispenser that meters by volume and not weight is incapable of being precise to a tenth consistently.
If you want loads as accurate as the scale you seem to be seeking, you need to charge light and trickle up manually- no volume metering system will do it.
I'm considering removing the case activated powder drop and just putting a funnel drop for charges dispensed via a Chargemaster or other "weighed" system for times when precision is more critical.
JMO YMMV
