Criteria for ELR Central World Record (03/2017)

Free PDF

As long as there have been long range weapons and men to fire them, there has been a quest to hit targets at the farthest possible distance. This basic idea drive is the same thing that compels humans to race, climb mountains and excel at whatever they’re driven to do. In the pursuit of the most extreme, nothing is more profound than a world record. The idea of a world record is that it represents the greatest achievement within a certain discipline.

Regarding Extreme Long Range (ELR) shooting goes, many shooters have attempted hitting targets of various sizes at the maximum possible range. These attempts and accomplishments are valuable steps in the advancement in ELR shooting. However, in order to establish true ‘records’, it becomes necessary to set standards for target size, conditions, equipment, timing, and evidence of success. Without any guidelines in place for individuals to pursuit a common goal, there can be no comparison of achievements. A hit on a 3 foot target is more difficult than hitting an 8 foot target, and that’s easy compared to hitting a 100 foot rock. Likewise, hitting any size target on the first shot is more difficult than hitting it once out of 20 or 50 shots. Speaking of equipment, the max range of a 16-inch gun on an Iowa class battleship is over 24 miles. Clearly some standards are required to scope the goals and intent of any legitimate record.
