I got a pack of these back in Aug. to try out .. I was impressed with the accuracy and sharpness .. I was told there were not replacement blades available (?) ... they are a 1.25" cut on the 100gr, not sure about other weights ... I shot low at distance on my 3D target and hit the metal rod in the leg, the tip did curl on that one .. Im hunting with one, but have yet to use it on a critter ...
