I was taught just to put a small washer onto a feild tip with a hole just big enough for the threads to go through but small enough so it dont slide down the arrow. Works good for grouse and quail,and my buddy got a jack rabbit too with it. I always keep one of those arrows with me but I always either get two shots or loose/break my grouse arrow and end up using a broadhead and that works too. But expensive for small game but usually too much fun to pass up, and that only when I am at camp or heading back to the truck.
