Oh actually GFK, how do I get the handle to the front of the bullet? By creating a pivot there and parenting the bullet to it?
You can do it that way, OR you can set the handle position in your 3d modelling package. How you do it depends on which package you're using.In Max4 (which I use), position the front of the bullet at 0,0,0 (where the thick black lines cross), highlight the bullet and choose "Export selected...".
