I'm not Mule Deer, but I'll point out that Lapua has made small primer .308 cases for a while at the bequest of match shooters and it doesn't seem to bother anyone. Those cases have the potential of being used in all manner of rifles. I'd imagine their thinking is along the same lines on a small rifle creedmoor case, it's more geared toward match shooters. I don't see a problem with a modification that makes a case stronger than the original. Most know that trying to read pressure from the case head isn't reliable so I don't see the argument that the new case won't show pressure signs as compelling.
