[G.M.]

There are special crimpers for the bullets. I have several that I had for years. These have plier type handles, there is an open circle in the middle of the complete round end. There are 3 or 4 little sliders that move into the center of the hole when squeezed. The wire is striped inserted in the bullet with the stripped end sticking out the end of the bullet about 1/8". The bullet is inserted into the round hole in the crimper and the sliders line up un the groove right behind the bullet end. As you squeeze the handles the siders move in and crimp the connecter to the wire. I always solder the wire end with small diameter solder and trim the end with a sharp cutter.
