The Sled makes zeroing for big game less punishing and more efficient by taming heavy-hitting loads that can send you into the field flinching. It uses 25-pound bags of lead shot (not included) and its steel-tubed frame to reduce recoil by up to 90 percent. Caldwell claims that one bag of shot on the Sled will reduce the recoil of a 12-gauge slug by 82 percent. 573/445-9200, www.battenfeldtechnologies.com
