I do many of the things Charlie described above, the only thing I do different is that I don't us hot melt glue, and Charlie...LOL, I don't lose points either. I use Gorilla Glue. It sets up slowly, but it gives me plenty of time to correct wobble if there is any.
I have used JB Weld and JB Quick, however as you know, once it happens it is forever!!!! So if you change heads a bunch, follow Charlie's advice.
Arrows with heads that get chipped and dinged become my small game arrows, or my broadhead practice arrows.
