I have a Herter's 7X57 die that will pull the rim off of almost any case regardless of the amount of lube that is used. The die does not have a very good internal finish and it is about .004 smaller than other 7X57 dies at the shoulder. If you run into a 50 year old die that looks new, beware that there may be a good reason for it to be unused.
There are not too many good rules when there is such a wide variety of cases, dies, shell holders, brass, lubricants and rifle chambers.
Revolver shooters have no idea why rifle shooters have problems because they only size small cases with big rims. The same goes for those of us that size 45-70 and 50-70. The big rims never pull off. With .223/ 5.56 rims - beware.

I always clean my dies out with automotive mass airflow sensor solvent about every 50 sizings or so. Dont like a lot of lube "in" the die. If cases are sizing hard enought to stick with proper lube, probably best to check your reamer or chamber dimensions.
I fully clean the inside of my dies using automotive MAF cleaner. Never pre-lube my dies before use. If fired cases are sizing hard enough to get stuck in a clean die when using a good lube like imperial wax or whatever else, you probably have a chamber that is out of spec. I've seen this with factory rifles, but even then, I've never stuck a case that was lubed properly.
I will usually lube the entire body and shoulder of the first case in a clean die. After that, I just hit the shoulder and about half way down the body. No issues
