Thats the way I do mine,I use saran wrap to hold the insert snug enough for bareshafting before I glue them in.It also depends on the type of target you are shooting into.I use a 2" thick foam target in front of a soft bag target,the foam target holds the position of the arrow and the bag doesn't grab tight enough to pull the insert back out with the saran wrap holding it in.This method works good but you need a soft target to shoot into,I do all my carbon tuning this way.I don't like to use any heat or hot melt glue for tuning carbons and it is quick and easy to do this way.
