I FL size everything. I haven't caught on to neck sizing yet. I have reloaded an honest 2500-3000 pistol and probably 500-600 rifle rounds so I'm still in the infancy stage. I have never used a L.E. Wilson cartridge gauge or an RCBS mic gauge either. I don't have a concentricity gauge and I don't weigh my brass. I want to take my reloading to the next level some day soon. I plan to purchase a rifle that I hope will get me into bench rest shooting up to 500 yards while waiting for hunting season. To answer your question, what works for me is to FL size every piece of brass I process. New brass, especially revolver pistol hunting ammo, also gets a shave and a haircut as I like to keep them uniform and separated from the rest of the flock. I do get complements on my ammo; "I like that crimp" "nice looking brass" "nice fireball" "very accurate" and I appreciate the fact many people see that I take pride in my work. I wouldn't skip a step to save a little time if in the back of my mind I thought I could have done reasonably better in the final product.
