The Lyman Magnum Inertia Bullet Puller is designed to safely disassemble a loaded round in seconds with out damage to the bullet or brass case. Just smack the head on a hard surface until the bullet comes apart from the brass. The head design has been newly engineered to allow the puller to be used on a full range of calibers from the small 5.7x28mm FN to the largest magnum case. The "full size" ergonomic molded handle with rubber insert will provide a comfortable secure grip so the tool wont slip while being used.
