I've found that like Tech, accuracy has improved slightly. That's with Lapua and Peterson brass which is all I use now. Annealing every reload, neck tension is more consistent. It shows on my arbor press which has force measurement dial indication with which I reload my 6.5 Creedmoor and 6 PPC. On larger cartridges, I can also feel it on my Co-Ax press which isn't the most subtle of presses out there. My SD's have dropped into single digits also.
Not for everyone, but a worthwhile addition for those seeking the best accuracy and of course case life.
