That matches my experience. Starline has about half the weight standard deviation of Remchester. They fall down in comparison to Lapua and Norma rifle brass in terms of neck and body wall runout by about 2:1, but that's the only flaw with the potential for a measurable increase in group size, but how much depends on bullet choices. On the plus side, as compared to Remchester and LC and other military brass, Starline flash holes don't have burrs. I bought 1000 of their 308 Win cases last year, and they don't show any burrs at all. That has meant better ignition consistency with some ball powers (2520, for example). They behave like 70:30 brass, which is best for reloading life, IME. With 44 Mag and other pistol brass (I"ve got another 1000 of their 45 Auto cases I am about to start using), I can't find any measurable accuracy drawbacks, and their reloading life cannot be surpassed except, perhaps, by ADG, which costs more. So I am pretty well married to them for revolver and pistol brass of all chamberings, and if you turn rifle case neck walls to uniform thickness, you've pretty much got them zeroed.
Overall, a good value.
