When you say, "lubricate cases"...

I use Imperial Wax for rifle and Hornady one shot for pistol cases. For the pistol it's makes things easier for me; brass in a gallon zip lock bag couple of sprays shake let dry and away we go.

I don't unless I have to, primarily because I hate adding steps to the process. With straight wall handgun cases and carbide or nitride dies, I do not lubricate except with .500 S&W. Those huge cases require far too much leaning on the handle, so I get a little Imperial wax on my fingers and make sure to feel up the cases as they go into the press. Then the sized and deprimed cases go into the tumbler for a while to get rid of the lube.

Rifle cases get essentially the same treatment, and I do make sure to get a slight bit into the necks, to ease the process and prevent stretching. They also go through the tumbling process again. You just have to check each case afterward to make sure nothing gets caught in the flash holes.

I do check mine, but I don't worry about it overmuch if I miss one. Primers are real efficient in clearing flash holes.
