You get yourself a set of Redding bushing necksizing dies, remove the decapper and expander ball (remove your spent primers with a Universal Decapping die), and get yourself the proper size TiN bushing. In addition to not having to use any lube whatsoever, you are also working your brass much, much less. It's a win/win situation.

Bushing dies are, IMHO, the least desirable "solution" for all but BR shooters. Why? 'Cause our case necks vary in thickness. That means that when sized in a die without an expander they inside diameters also vary, which changes the bullet tension randomly.
Perhaps the ideal solution would be to use a body die AND a Lee Collet Neck Sizer. The Lee die does not need lube at all and it works the necks only the amount needed as it sizes down to a consistant inside diameter.

That's just plain bunk. If I had varying amounts of neck tension, it would surely show up at the 1,000 yards I shoot;it does not. Seating the bullet in the neck does exactly what any mandrel or expander ball does: forces any variation in inside diameter to the outside. This is empirical data, not something gleaned from the internet.

I have to agree and disagree with both of these.
Bushing dies are great if you turn the necks or ream the necks.
I wouldn't say they are just for BR shooting, but would say that if you take a ball mic and check the neck thickness on 10 cases you will probably come up with 5 different measurements if not more.
This will cause different neck tension as the bushing die has no expander to push the difference back out.
