how big of a difference will an arrow that is a tad to long make? i got some 32 inch arrows and i have a 30 inch draw bow? i heard that the arrow should be 1.75 inches longer that your length. how big of a difference is that .25 gonna make thanks for the input |

Depend on how close you are to being over or under splined , check out the company's charts and see if it still works. Most likely wont be a problem. Some people cut them shorter, I tune each type of arrow to the sweet spot. You might just have to bring down tip weight if a arrow is a little long. |

I agree with ml271, find the spine charts, and/or change your tip weights if need be. But most likely, it won't be an issue. It's going to depend on the arrow and the bow as to how it shoots. I shoot a 28.25" arrow with a 29" draw. The drop-away rest I shoot sits back on the shelf, so I can get away with a shorter arrow. Some people like the safety factor of having the broadhead or tip a little further away from their hand if you knock the arrow off the shelf. The correct way to measure an arrow is from the bottom of the knock groove to the end of the arrow shaft, not including the point, broadhead, or insert. So if I went by the 1.75" longer method, I would need a 30.75" arrow, but I use arrows 2.5" shorter. A lot of people will take an arrow, draw it back, and have someone mark the shaft an inch away from the most forward part of the rest. Since there are many factors, like different rests, it's really something that needs to be measured for your specific bow. Good luck, happy shootin'  ETA: If you would like help with the spine charts, just post the draw weight, arrow brand and type, what weight tips your using, and someone will show you how to get all the info you need. |

I recently went with a stiffer spined arrow. I shoot a Mathews Q2 at 30" draw, 70# and was using ICS 400's. They shot okay but iI would occasionally get a flyer and though I got good groups I have long been used to drilling holes in holes. But I never got that type of grouping with this bow and because I so much liked EVRYTHINg else about the bow I figured the trade off was worth it. But watching my buddies who never shot better than I do just that I started wiondering what was going on.. I figured the bow was the problem and it just wouldnt work for me. I was going to sell it and look for something else.. But then I started thinking and figured I would try a stiffer spine. So I tried the ICS 340's and cut them to be one inch beyond the rest so not only were the stiffer with the same length they would "act" stiffer even moreso since my previous arrows were about an inch and three quarters beyod the rest. My first three arrows I shot were touching each other and the 4th was a "Robin Hood".
So even though I was recommended to shoot the 400's a stiffer spine worked better for various reasons.. Archery is a lot of exerimentation. There is no set formula that will work all the time for everyone. But once it all comes together, that arrow flying downrange is almost magic.. |
