Small bae die sizes lower on the case and a smidgen smaller. If you reloaded and shot those cases in your gun, without problem, continue. You may have a larger chamber so they won't fit in SAAMI gauge. Range PU of BO or 223 may be from another larger chamber gun. Chamber the large cases in your gun and see if the bolt closes. Note also. Over pressure loads expand the case by the head first. I got one that looks like a belted magnum due to an over pressure load. Had to prey the bolt open.
Whatever!
Spell check doesn't work in Chrome, so if something is spelled wrong, it's just a typo that I missed.
I convert 99% of my 300BLK, and 277WLV brass from LC brass and never had this issue, it may just be a combination of dings on the rim and gauge variation. Since I form my brass, I bought a Sheridan slotted gauge to see exactly where my sizer was having issues, and at first I had a few. Turned out that my Lee case holder was a bit tall, I took a bit off it and worked, but RCBS case holder worked right off (wish I tried that first). Though I figured out the issue using Lee dies, the Hornady, and RCBS didn't have this issue. One thing I noticed on the LC brass was that cases fired through the SAW were harder to size, and the extractor dinged the rim more, so it may be cases like that that are giving you issues.
These are 277WLV but they look the same.

Rims too large ... pick up an Acme Rim Trimmer ... trims them pesky oversized rims back to where they fit the case gauge .
