The course specifies an unloaded start and the shooter has 11 rounds in his mag. Many do to begin a loaded start, but it is easy to forget. So that calls for a bump to Open:
6.2.5.1 However, if a competitor fails to satisfy the equipment or other requirements of a declared Division during a course of fire, the competitor will be placed in Open Division, if available, otherwise the competitor will shoot the match for no score.
Appendix D4, 9: Yes, maximum 10 rounds loaded in any magazine after the start signal
So, my question is: Isn't that a bit harsh? To ruin an entire match because of 1 extra round? Perhaps just a procedural would be appropriate?
