Remember that the manufacturer's spec is to strip about 1/2" to insure that there sufficient wire to grab inside the contact area and still prevent the insulation from entering the contact area. If you cannot see a little copper when looking into the contact after wire insertion, you did not strip enough. If copper is extending beyond the walls of the terminal after insertion, you didn't insert the wire far enough or you stripped off too much insulation.
