RK, it should also tell you that ONLY dry lube (powdered graphite) is to be used on the inside of the case. A liquid lube will ruin your powder and/or primers. It is also usually only necessary for bottle neck cartridges. The graphite helps the sizing button that passes through the neck and leaves the inside diameter the correct size to do so with minimal drag and helps prevent over working the brass or stretching the neck.
The only thing that needs to touch the inside of a 9mm case - other than the bullet - is the die used to slightly bell the mouth of the case to ensure the bullet enters without scraping the sides of the bullet. This is an especially important consideration for a cast or lead bullet.
If for some reason a liquid is used to lube the inside of the case mouth, it must be thoroughly removed.... not a fun thing no matter how it's done. The best way to do it is use a dry lube.
