Centrefire Silhouette RifleД¬entrefire Silhouette Rifle has fairly liberal rules governing weight and dimensions and allows shooters to use custom rifles based on a wide choice of calibres, actions, barrels, triggers and stocks. However, 500m Centrefire ranges are not as common because of the large amount of land required to contain both the range and safety zone. Most SSAA branches can accommodate the 100m range required for the Rimfire matches. The range is set up with the targets at their appropriate distances from a common firing point. Rifle Metallic Silhouette usually caters for centrefire and rimfire rifles, air rifles, service rifles and black powder cartridge rifles. Also, because the cartridges used for Cowboy Lever Action hit the targets with less energy than the handguns used in Handgun Metallic Silhouette, target damage and fall-out zones are greatly reduced. This match is conducted on existing Handgun Metallic Silhouette ranges and opens up Rifle Metallic Silhouette shooting to a larger number of shooters who wouldnвЂ™t usually have access to a 500m range. Silhouette shooting continued to grow in popularity, and in 2006, the Rifle Metallic Silhouette discipline was approved to run NRA Cowboy Lever Action Silhouette as a national event, with the first National Championships held in 2008. International matches are a common event, with SSAA teams regularly competing in NRA Metallic Silhouette Championships. Each year, there are state and national championships, as well as postal competitions. The sport originated in Mexico in the early 1950s, arrived in Australia in the late 1970s and is now a sanctioned and popular discipline of the SSAA. Rifle Metallic Silhouette is a sport in which rifles are used to knock down metal targets at a variety of distances.
