NRA MR-31 100yd HPR target
The MR-31 scales the Mid-Range MR-1 down so that the prone slow-fire stage of NRA High Power’s National Match Course, normally fired at 600 yd, can be shot at a reduced distance. That stage is the course’s largest — 20 of its 50 shots — and allows a minute per shot, sighters included.

NRA Marksmanship Qualification Program
The NRA dates the programme to 1903 and measures shooters against par scores in 23 qualifications, from BB gun to shotgun and multi-gun. Awards are ordered from the NRA’s Program Materials Center: the discipline’s patch at the start, then a rocker, medal, pin and certificate for each rating. NRA members who reach Distinguished Expert get its packet free, and those who earn it in 2 or 3 of rifle, pistol and shotgun become Double or Triple Distinguished.
Ratings are earned in order, from Pro-Marksman up, at the shooter’s own pace; a score counts only toward the rating being worked on and cannot be held for a higher one, and the repetitions need not be fired in a row or in one session. Distinguished Expert firing is witnessed by an NRA member, instructor or coach, unless it is shot in competition.

How it is shot
Course · Time · Convertible sighters · Perfect scores · Ties
- Course
- In the National Match Course that stage is 20 shots prone in slow fire; on its own the MR-31 carries 10- or 20-shot prone slow-fire matches, which NRA marks as a reduced target and distance course.NRA rules 7.4 and 7.14
- Time
- Slow fire allows one minute per shot, sighters included when specified; in the national-record courses on this card two sighters are fired and recorded in each stage, so a 20-shot stage runs 22 minutes.NRA rules 8.1, 8.2(a) and 17.5
- Convertible sighters
- In slow fire, where the match program allows convertible sighters, a shooter may keep the second sighter, or both, as record shots, telling the scorer straight after the sighters and before any further shot.NRA rule 9.2(e)
- Perfect scores
- A shooter who fires a perfect score, all X’s, in an individual match fires on until a shot leaves the X ring; the extra shots are recorded apart from the total, as in 200-20X plus 3X.NRA rule 9.7
- Ties
- Ties go first to the most X’s over the course, then to the higher score and more X’s at the longest or simulated longest range, which in a National Match Course fired at 100 yd is the MR-31 stage.NRA rules 4.2(c) and 15.4

The card
- X ring
- The X is an inner circle that breaks ties without changing the total: the highest value on an NRA high power target is 10, so the inner circle is marked X, the Roman numeral ten.NRA Glossary, “X” Ring
