Another spine question

[tr23489]

I'm fairly a newbie at this, so please bear with me.  After spine testing my arrows, I have determined that they vary quite a bit.  Out of a dozen arrows, supposedly spined 45-50, I found that I had 3 or 4 that were in the 40# range. I'm not concerned with those that are a few #'s off.  Just the outliers.

My queston is this, do you try to make these work?  In other words, would you shorten them to stiffen them up and/or take away some point weight thus having different sized arrows in your quiver.  Even though they may fly well and are matched to your bow?  Just looking for your thoughts.

tr,  Wood arrows?  Was the grain(growth rings) all orientated in the same direction?  If those are completed wood arrows, When you spine tested them, ALL OF THEM should lay on the spine tester the same way.  Cock feather up or nock groove horizontal.

If you are using them for hunting you want them matched period. A matched set in spine and weight is very important for your best accuracy. You owe that to the animal. If you are roving and stumping or 3-D'ing and not really concerned about scores, it is fine to shoot mismatched arrows that fly well out of your bow. I actually have a set of 14 matched 45-50# spine I am doing now and the other 10 out of 2 dozen are off quite a bit, half around 40 and the other half around 55 and weight variance of up to 80 grains. I will leave the 55# spine long and the 40# spine I will cut an 1" shorter and use 100 grain head instead of 125. I will keep half the matched set to hunt with the others will be for play. Shawn

Sorry, yes, wood arrows.  I beleive I tested them accurately.  I even spun them and measured 3 to 4 times.

Agreed on having a matched set for hunting.  I do have that and that is the only way I would go.  In my mind, I was thinking mostly about stumping and target for the odd arrows.  I didn't want to just let them sit.  Was more curious with what you do with them

Thanks for the input guys.

Stumps, target, or make them into flu-flu arrows where spine isn't as critical due to the large feather drag.

Spine on wood arrows is measured parallel to the wood-grain orientation. In other words, apply the weight/force in the same direction or plane that a baseball would hit a wooden bat if you were holding the (Louisville Slugger) label either straight up or down and swinging horizontal. A bat or arrow is stronger "with" the grain than "against" it.

I don't know how suppliers who send out mismatched shafts stay in business. As a former shaft manufacturer, it really burns me up. Find someone who does it right, and stick with them. Cheaper is not better if you don't get what you pay for.

With field points you can get by with a few pounds off either way, but with broadheads, especially big ones, the spine has to be right!
