The wire I use is stainless steel leader wire, normally sold at saltwater fishing shops. I forget what size, I`ve been cutting off the same spool for years. I forgot to mention that the point with the wire has a roofing washer off of a Tek screw with a rubber washer on it. You put the wires in on both sides of the bolt, tighten down then bend out to 90 degrees. It is the best point of the three,hard to lose and cuts too. It`s the only point that kills blue quail reliably with body shots. Man they are one tough bird.This point weighs 148 grains, the one on the right 128,and the one onthe left 190. I`ve made only the one in the middle for years now,as it is the best by far.
