We seem to have this obsession to get an exacting seating depth, jump to the lands etc for perfection.
.001 off the lands or .050 can make be all I need and it must be precise. ( or devastating)
Oh yes, and the powder charge measured on a high quality digital scale.
Could these accuracy issues simply be a case of the case being out of alignment. Runnout?
I fussed like seating depths myself late into the night, using micrometer seating dies. I thought rocket science was like that until I stumbled onto the GS Custom site and its owner. They make CNC , land riding bullets that are seated to the drive band and load development was quick and easy.
Maybe this super uniform bullets should be started in a super uniform case?
Most handloader's speed case prep, it can be a blurr and slow down to seat the bullet perfectly.
I use a case gauge these days during the process now during case prep.
Any thought about bullet runnout as the primary culprit?
