Oh, a Baby RCBS Press...
Okay, anyway... I don't like Brett's suggestion. The reason is I don't and don't like the idea of using any oily lube inside a case neck UNLESS you completely clean it ALL out before proceeding playing with powder as the powder granules will stick to the inside of the neck and not fall into the case itself.
Many years ago I used a "Matchbox" with a layer of Graphite Powder in it and dipped every case into it to lube the inside of the case neck. Graphite is what smokeless powder is coated with to help protect against static electricity. It will not affect the powder and is easy removed with a case neck brush, well, most of it and the rest doesn't matter.
These days I use "Imperial Dry Neck Lube" (Graphite) and a "Imperial Application Media" (Ceramic Balls coated with Graphite)... Once my cases are coated with sizing wax/oil then I did the neck into the Graphite Coated Media. An alternative to just wiping the outside as I mentioned. It all depends on the case being sized and how tight they may be.
The Imperial gear is available from many places including BRT where I buy most of my precision reloading supplies from.. it's not expensive.
To test, go to a Auto Shop and get a Puff Bottle of Graphite Powder, put some into a small container enough to be 3-4mm deep and dip some necks then compare. If you like the result then buy the Imperial Kit.
Small warning, Graphite is dirty stuff, be carefull and don't spill it.
It's all a learning curve.
