I ran through a good bit of reloads trying to find the magic load for the 123 gr SSTs, and then switching over to and sighting in the night vision scope. As I resized fired cases, I noticed that very little trimming was needed on those cases. Case length growth was minimal, compared to my 223 and 260 fired brass. The brass is Starline. The loads are neither minimum or maximum, at 27.2 gr of H335. I found the very minor case growth to be surprising. Is it due to the Grendel being a lower pressure round?
