Bart B, As to the classification please show rules "Once you’re assigned an NRA classification, you have to shoot at least the scores that got your that classification else you dropped to a lower one" .
This is what I read.
A competitor will be reclassified downward only upon request in writing by him to the NRA, and only on the basis of at least 320 shots (180 shots for Prone Classification) recorded as prescribed,fired subsequent to the effective date of his current classification. If his average on this basis so justifies he will be reclassified downward accordingly.
