I have a few techniques....for full length sizing 'large rifle' cases, I use a foam pad to lightly lube my brass. One corner of the pad I have a 'wet' spot....more lube than the rest of the pad, just push the neck straight down into the wet spot. You really don't need a lot once you start going and the expander ball is lubed...maybe a little more at first. 2. For small rifle and cases that pass through a little easier...I roll the bass very lightly so that only the main body gets lubed, then I dip the neck in Imperial Dry Neck Lube, (graphite) ...works wonderful...just tap the case when done sizing and you don't have to worry about cleaning wet lube out of the neck, or contaminating primers and powder. On the downside...the necks get black, and so will your fingers. 3. When I can...Neck Size Only...with just the graphite. I have tried adjusting Full-Length dies so they just neck-size...but it dosent work well with all cartridges. I wish I had bought neck-size dies all the way back in the beginning when I first started buying dies. For my 35 Whelen Imp, I bought the Redding 3 die set with full-length and Neck-size dies. I have only used the full length die once....I just dip in the Imperial (graphite) , size the neck and they are done..The necks get black....but NO CHANCE Ever or fouling primers or powder. Of course these cartridges should ONLY be used in the rifle that fired them.
4. Pistola....or straight walled cases....also graphite only. Some dies say they do not require lube for pistol cases, but I use a little Imperial anyway. I just wish they could come out with neutral colored graphite.
