I got that pic in an e-mail yrs ago. It had nothing to do with spine! The arrow was damged and it was shot......... a damaged arrow may cause it too be underspined but I don't think thats what this about. You should post pics of the guy with the allum arrow in his hand too...... overdraw back in the day. Or the one of the guy with a BH stuck in his skull...... guess he stood up in front of a friend that was about to shoot. I'm no pro but I would think a pic like this the guy would have to be shooting .500 spined shaft on a 90lbs+ draw weight. That pic has little or nothing to do with this thread........... unless your the guy that got the arrow thru your hand[:-]

While I agree, that it really was very likely a damaged arrow, it does have a little validity, because shooting underspined arrows can and does result in arrow damage. I've cracked a few nocks, and driven a few inserts a little deeper than intended over the years by not being as "in the know" as I should have been. Trying to get that SPEED, can make for a potential disaster, not that this was the case in this picture, but it kind of sets forth a mindset of making sure you get an appropriate spine. One thing I always do before I shoot an arrow is tap it on my riser (except when hunting, and those are checked before I leave my truck) making sure I don't hear that sound of a lose tip on and arrow with a tight tip. If you hear that sound, that arrow goes to the trash pile.

Can you use a heavier broadhead to improve flight? I just went to a stiffer spined arrow, .300, and my broadheads are landing to the right of where my field points hit. I am shooting 100gr. heads.

i am just wondering...everyone talks about spine and how to get the correct spine on an arrow....however,,,,if you are overspined or underspined what damage does this cause??

bad arrow flight? is it bad for your bow? i am just wondering

Underspined....broadheads will group right of your field points, overspined....they'll group to the left.

More weight on the head will soften the spine;)

RE: problems caused by spine issues?

You may have a tuning or clearanceissue, not a spine issue. Trying shooting one of these arrows with no fletching, and a field point - at 20 yards - see where that hits relative to the same arrow with fletching.
