What about just using hot melt glue for inserts in ACC's?
It has been working since the invention of the aluminum arrow.
Why in the world would any one use JB Weld for inserts?

Usually when problems happed with aluminum arrows and inserts it is the super glues that have been used.



Is theshoulder of the point the same diameter of the insert and then tapers out to a larger diameter like this


or is theshoulder justbigger than the insert period?

If it's just bigger then they are the wrong size and you just need to one size smaller and they will pull out of bags just fine. He probably ordered you 5/16ths which is what a standard carbon arrow like a Gold tip or BemanICSuses.
