Well, we dont like the term ABD.  The term to use is APD.  Bounceback is 
good, penetration is bad.

For APDs on fiberglass bolts or arrows you can use any of the siloflex 
designs approved for use.  Examples are at:
http://www.combat-archery.com/100160apd.htm
http://www.combat-archery.com/7580psi.htm

Or you can use a Golf Tube APD.  Examples at
http://www.combat-archery.com/gtapd.htm

Or you can use the commercial Asgard APD which you can buy from  
http://www.northstararchery.com

For crossbows I recommend either the commercial Asgard APD or the 
Square-cut routed channel 160PSI siloflex design.

The blunt does not have to be a tapered UHMW blunt  core does it have to 
be 2" long.  The UHMW core can only be 1" long with a 0.5" deep hole 
drilled for the shaft and leaving  0.5" of solid UHMW in front of the shaft.

There are some good links via the manuals and reference page on 
http://archery.ansteorra.org look at Vivaines pages for some pretty good 
directions on how to make bolts as well as some good pictures.  Likewise 
there are some articles from various AoBs, etc that will be of help.
