Indoor ranges come in different sizes, lengths and can be designed for multiple purposes. While 25 yards has become the standard distance for indoor ranges, there are many successful businesses with shorter distances such as 15 yards with no ill effects or complaints from the shooters who frequent them. In recent years, longer distance, rifle rated ranges out to 50, 75 and even 100 yards have proven to be successful in larger markets due to the popularity of mid-caliber rifles such as the AR15 and AK47, as well as hunters and precision shooters. The size and design of your range should take into account the population of your expected market, availability and types of shooting areas near you (including competitor ranges and free outdoor ranges), geographical weather, if classes will be offered and what types, local politics, ordinances and general acceptance of a range business.
