Hot melt will always fail along the hard and slick interior metal surface of the point. To prevent loss, you use a M8 (metric 8) thread cutter and cut two revolutions into the inside of the point ferrule.
Even with "cheap" hot melt, they won't come loose anymore. Ferr-L-Tite is one of the worst hot melts anyways. Way too hard and brittle. The high strength glue sticks for the glue guns does just as well. If you use hardwood arrows or repair pieces behind the point and use a high quality taper tool that will really just shave off a thin piece of wood an leave a supper slick surface, just use a small pull saw held at 90 degrees and scratch the taper. That will give enough roughness that there will never be a failure along the wood.
