NRA rules for small bore shooting comps

[Hemmers]

As Rutty says, Class X can sometimes be a "National Squad" class.
The NSRA's "National Classifications" are based on the Bisley and Scottish Weeks, where the top and bottom 10% in each class are promoted and demoted respectively. At the Scottish and Bisley Smallbore Weeks, Class X can only be reached by being promoted from Class A at a previous meeting (and not subsequently being demoted at a more recent meeting!). These are the official classifications.

However, since not everyone shoots those meetings, not everyone has a national classification, so have to enter according to their average (best 10 of last 12 cards shot). County or club level meetings may vary the average boundaries for each class to ensure a good distribution of entries in their events, so the standard of "A-Class" may be higher or lower than the national definition. Some (like Hampshire) don't - and at their summer English Matches end up with about 40 people in Class A, 10 in class B, and 2 or 3 across C&D (they have no X-Class).
