Hey NewIndian,
Like those guys said it is easier to make an extra set, after target/stump shooting some of my shafts wont come out at all. I was hoping to be able the change them out as well. But if you really want them to stay, I usually set my foreshafts in with a little saliva, it makes the inside of the shaft swell up and lock it in place. Did I not show you the couple of sets I had at the gtg?
