I've been reloading for over a year, on my Dillon 550B and recently bought a Redding Competition Seating die to reduce variation in my .45acp loads. The rest of my setup is a EGW U-die and a Redding taper crimp die. I expected to see next to no variation, but that is not the case. I'm seeing as much as .003 variation. After much tinkering I got the variation down to +/- .001 consistently with the occasional -.002. Am I being too anal, or is this all I can expect of this specific set up?:banghead:
