I have had really bad luck with hot melt.......lost 8 of the 12 inserts I originally put in my hunting arrows this year in morrell bags because of the stuff. Then I used gold tips glue for inserts and no more problems. You can actually pour a bit of acetone in the nock end of the shaft and let it sit like that (some will drain, put it in a place with this in mind). Then I can get them out with pliers on the tip if/when I need to. Usually I don't have a problem though, I just spin them and take the true ones and use those for broadheads, and the ones that don't spin are used for field points.
