That’s interesting. I haven’t had a point be driven back into the shaft. The brass inserts I use have a collar. I’ve had shafts split a little, but nothing that allowed the point to be driven back. One thing I didn’t think about when I wrote yesterday is that I put aluminum collars on my stumpers, both front and back. You might consider trying one of those. Prior to using the collars I might get some splitting on the end of the shaft after a solid impact with a rock, even on the nock end. Now I don’t have that problem at all. They only weigh 5 grains, so adding one on the front wouldn’t change much at all. best, dwc
