I have noticed lately that my older practice arrows fly worse then my newer ones. Can they wear out the more you shoot them? It is notacible with both fieldpoints and broadheads but more noticable with broadheads. Thanks in advance. Hunter
Yes, they can. It is the spine that changes and becomes inconsistent. On new shafts, especially the better quality ones, the spine-around-shaft is pretty consistent. That means that wherever you should measure the spine, say at the 0, 90, 180, 270 degree mark, the spine, good shafts anyway, should be within .005 of rating. As you shoot the arrows over time, the constant pounding in the target will begin to break the spine down, up and down the length and around the shaft. It will not break down evenly so the arrow, when shot, will not flex consistently and that causes that particular shaft to not group with the others. Arrows like that are good for squirrel hunting and stump shooting. That way you can blame the miss on a bad arrow .
Thanks for the info! I figured that was what it was but just wanted to be sure. Your idea on the stump shooting tho is a darn good idea, thats gana be my new excuse from now on!! Thanks again!!
Yes,arrows do wear out but high end shafts tend to last a really long time. YEARS and YEARS. Cheaper shafts may lose their spine more quickly. Nocks tend to wear out and give you more headaches than shafts weraing out. However,I would double check the old shafts for clearance issues and make sure they are the same spine as the new ones.
Look at your nocks. Hitting them and just going on/off arrows changes them eventually. To me they are very important, they are the only part of the arrows that sends it. Replace your nocks (relatively cheap) and I bet you will shoot better.
You can shoot the spine out of arrow shafts without question. A few league guys have shot the spine out of target arrows in as little as 4 years. Target arrows are typically lighter and run on the lower end of the scale for spine requirements for your set up, so this is obviously a contributor to spine failure. Change the nocks like they say but throw broadheads on the shafts(to whack out the ballistic coefficient and amplify tuning problems) and you'll find arrows that don't want to play no doubt.
