I tend to treat bolt action rounds like a surgical instrument and do a lot of case prep, because the rifles were built for accuracy and lot of money invested in glass, barrels, stocks, triggers etc... I don't want to drive my race car on regular gas, don't want to feed my precision guns regular fodder.
Now having said that, my U.S. Service rifle coach, is a High Master, that means his scores as a rule are 98% or above in all conditions!

He loads on a Dillon 1,000, and has a good formula. He starts off with once fired brass, He only loads them 3 times, He uses Winchester primers because of the way they are oriented in the tray, cup side down, He then paints the primers with spray paint, white for the 1st loading, red for the 2nd and blaze orange for the 3rd, on the 3rd time he leaves the brass on the range. He is loading for the M1a and AR15, the Dillon does have an electric case trimmer.
I have 2 Dillon 550 b's set up for small and large primer that are primarily pistol. Loading for .308 for my M1a's works well, I have not tried .223 yet.
