Welcome to the site. Check out this thread
bullet runout

Runout is essentially how straight your reloaded round is. If your chamber is perfectly straight/square and the brass is perfectly consistent in thickness (not gonna happen) then straight rounds are easy to make.

Runout is measured in 1/1000" of an inch with fixtures like this, Concentricty Gauge

With good brass and good processes, you should be able to get .002" or less runout.
