BigJakeJ1s: "I have two experienced reloading friends that stuck rifle cases in their only Lee sizing dies they had (yes they were using the appropriate kind/amount of lube)."
Maybe so. But, suggestions of experience and lube aside, I doubt it.
Cases stick because they aren't properly lubed, not because of any lack of mirror polishing in the die. I have found some individual size dies from almost all makers, including RCBS and Redding, that lacked the mirror inner polish, they all worked just fine too. On average, Lee's sizer dies are as well polished internally as any others.
I have lapped out a few size dies over the years and then resized cases both before and after the dies were polished. Never saw any difference IF the brass was properly lubed first. But, I do like that shine and I like to make it so, no matter what the original internal finish was like!
