[QUOTE="davidfrances, post: 1007357, member: 85142"] Thank you for your reply. I now have a few more questions - How do I know (or determine) which size bushing came with the factory dies? I measured the neck diameter of some of my old 1x loaded rounds. A 20 round sample was 100% .333 These are my reference bullets. I measured the neck diameter of the six (6) I was able to successfully load this morning and the smallest average diameter was .332 If I understand correctly, I simply subtract 0.001" from the cartridge that had the smallest average measurement, to allow for a slight amount of spring back and create a proper press fit for the bullet. That means I should buy a bushing of .331. Correct? Redding's website says .001, you say .002 - .003 Should I bracket this .331, and also buy a .330 and a .332? Or .329, .328 using your guidance? Thank you again for your help. Thoughts? [/QUOTE]
