Here's the thing. Why do most of them slide right in, and only a few of them crush the cases? I mean I am using the Hornady dies to size all of them. I have a Lee Universal expander but it is a pain in the butt to use, and I do not have this problem at all if I used a jacketed case instead of these Xtreme copper plated cases.

Most likely you brass isn't all the same height. You set the die for some taller pieces, and one short piece that doesn't reach the flare get by. When you put a bullet in the short piece, the plating tears.

I loaded some in my 357 at 1000 fps and they shedded the plating. I have also noticed that there is more recoil when loading them with the same charge as jacketed bullets of the same weight. Softer bullets can raise the pressure  because they offer more resistance.

many manufacturers say to load plated using low to midrange jacketed data

Did I mention I trimed them to length, and chamfered them inside and out? Heck. I even swaged out the primer pockets,

I have a little problem with Xtreme bullets. I'm not sure their quality control is up to snuff. I was doing a bunch of .223 using their 55 grain bullets. Some of them were crushing the case. (Not all of them, some of them) Made me wonder if their plating thickness was even.

Xtreme .223 aren't plated.  They are jacketed.  I just loaded a full box (500 PCS) and never had an issue using LC brass.

Whatever, non x-treme, no crumpled cases, X-Tremes, lots of crumpled cases. That would tend to make me think it is not being caused by me.

At the risk of getting a bit off topic... That would indicate varying diameters. Did you measure, by chance?

Nope, should have, though.
