What else do I need if anything and how do I do this? Does it need to be done in small steps and if so how do I do it in small steps without bushing style dies? The dies I have on order are redding D series dies. Any help would be much appreciated.
there are three very important steps here
1. lube case
2. insert sizing die into press
3. use press to cycle brass through sizing die
One caliber isn't anything but a walk in the park, especially down.
If you specified tight neck you may have to turn your necks a bit, but otherwise size, trim, load as usual.
