Lee Ultimate Die Set in 6.5CM vs Concentricity Gauge. Can Lee Dies produce Precision Handloads?

I've always wondered if Lee dies can stand up to making precision handloads. I put to the test the Lee Ultimate Die Set in 6.5 Creedmoor and see how much or how little run out these dies implement on our cartridges. Brass Prepping is the most important process on our handloads. Weight sorting vs Volume sorting? The little variation makes a huge difference and I show this using a program called Quick Load.
