Tip originally from Ferris Pindell about 1972: When neck sizing with a bushing get a set of three true CARBIDE bushing to take care of your case necks on a given cartridge. For one thing, they are round unlike many of the commercial steel and coated bushings. Buch Lambert used to provide me with all of mine but Bob Mundy (I think) can get them. It takes a while and they are not cheap. But they size necks very nice and burnish them as well -- they look good.
Additionally, Ferris told me to size just a small part of the neck with your bushing die. Let the bushing float but size only about 1/4 to 1/3 of the neck. You might have to go up on neck tension but that will show in your testing. Of course, the unsized portion of your necks fit nicely in the chamber, and if you have the correct neck tension, you have less chance for bad run out on the partially sized necks -- easier to get consistent neck tension and bullet release -- better ES in my testing over the decades.
Ferris would ever turn the major portion of the necks less than the portion being sized and holding the bullet. It sure worked for him.
Remember -- just a tip and food for thought.
