Caldwell AR500 Rimfire KYL Ring Challenge Target is a new take on the traditional KYL design. This KYL target uses rings instead of the traditional solid paddle targets that decrease in size. There are five 3 diameter targets with holes in the middle of each, forming a ring target. The size of the hole in the target increases leaving a smaller ring target as they progress. The most common way to use the target is for shooters to start with the largest target and accumulate points for each target they hit. If the shooter misses, they drop back to zero. This tests a shooters ability to judge their limits and see how well they stack up to others. Targets are constructed of certified AR500 steel and can withstand a lifetime of impacts from any rimfire cartridge including 22 Magnum and 17HMR.
