I carry a bar of Ivory in a fanny pack on the 3D range works like a champ. Rub a little on the shaft by the tip right before the shot, doesn't seem to affect flight at all. Works way better than any lubricant I've tried, a 2 finger pull every time.

I've heard the liquid Ivory also works good in a tube, but I tried someone else's and it didn't. I don't know what formulation he used though, it may take some experimentation to get the same results.
