30-06 Dummy, differnet h/s?

This is a fluted dummy with one hole. As you can see, it is from F A 38 but then it has NM next to the number. I looked thru Chris’ book and saw no mention of anything like this under FA. Comments welcome.

NM= National match case

Hmmm! I should have known that shouldn’t I!
I think its time to go to bed… I was thinking New Mexico!
