I have been able to reform points on some of the sheds we have found. I have used Bondo from auto body shops, to form the point. If you have enough base left you can put a screw or heavy wire in before you start adding bondo and shaping. Once the shaping is done you will want to texture and when it gets cured real good then I mixed some wood stain. Just played with it till I got it right, testing on old pieces of antler till I got the color I wanted then apply sparingly. On the wall it looks pretty good, If in your hand and you know what to look for you will see where the new point was added. Also note that all I have ever done this on was elk antlers.
