Re: Loading rifle with dillon progressive
for myself, I set up each die indivdually, in succession from 1 thru 4, and then check the result on the first full set of bullets as they progress thru the press. Haven't thought about doing the other way, and may try that just to find out if I've missed something.
I do change tool heads as I change calibers, but I'm somewhat anal, and have a tool head already dialed in for the calibers I usually load in my 550 - btw I run three, one each for small and large primers, and one for new stuff/calibers/tests. If you get to changing tool heads among presses, and changing primer slides, sometimes things can get out of whack. Maybe the throat dimensions vary slightly?
