Hi David, what you are encountering is not uncommon on the Axis shafts. First thing you want to do is get an ASD, thats arrow squaring device, if the point end of the shaft isn't perfectly square it creates a pressure point where the point seats against the shaft. Thats a lot of pressure exerted at one tiny spot. That is the name they are sold under, ASD. I think Kustom King, Black Widow and 3R sell them.Next thing you want to do is use a footing on the front of the shaft. You can use eastons BAR's, broadhead adapter rings. Or use an inch or so of tubing(like a alum. arrow shaft) to foot the front of the shaft. I use 2020's on 340s but haven't use any on my 500's yet.I use all the methods mentioned above and don't have any of the splintering you are talking about since I have gone to these methods. The Axis is a great shaft just square the front and foot it and you'll have a very hard time breaking one. I've been shooting them for about 6 years now and won't use anything else. Feel free to PM me if you need any further questions answered. Frank
