    Ive been shooting archery for the past few years. Finding land to hunt rifle on in CT keeps getting harder and has pushed me into buying my first bow. Now im hooked i love it. I started cutting my own arrows and have come into a problem. I have a pretty extensive inverntory of reloading supplys and have the ability to weight my arrows to the tenth of a grain. Ive started cutting and assembling a few and found that the length varies about 1/4 inch from longest to shortest. Ive matched the arrows to about .2 grains. My question is what is the more important factor; perfect length or perfect weight of an arrow.

    If your just a hunter and not a target man then IMO a tenth of a gram here and there won't effect you at all. Most arrows and broadheads will vary some but IMO proper arrow spline and center shot out weights having a few grams off

    Do not change length to match weight. This will change the dynamic spine of the arrows and will result in an unmatched set of arrows.


    No real need in having arrows that close in weight for hunting and even most target venues.



    It may be necessary in target venues like fita field but they aren't using hunting shafts for that.

    I do group my arrows by weight. However its more important how they shoot. I find there is always a handful of arrows I have better groups with. For some reason this for me holds even more true when I switch out to broadheads. Maybe its because I am lazy and don't tune my hunting bow like I use too. Do what works best for you! I agree with not cutting the arrows different lengths.

    Thanks, i cut the rest to size and sorted them by weight. Ill be testing them tonight.

    I started with 12 cabelas carbon hunters. Not the best arrows on the shelf, but for just starting out theyre decent. I cut 8 to exact size and matched the final weight with the slick tricks broadheads. Then i matched the last 4 arrows to exact weight and matched final weight with the broadheads. At 40 yards the arrows grouped by length out performed the arrows matched by weight. The groups were tighter and the arrows stayed with a consistent flight from 20-60 yards. the cut to length arrows were exact to one another with final weighted differance of 1-6 grains. The weighted arrows were within .5 grains but varied by 3/8 inch.

    Weight just isn't that critical when it comes to hunting distances with arrows but spine is. Like I stated earlier, the length of the arrow greatly affects dynamic spine. Each arrow will react differently to the shot when spine is different.

    yes i see that now. I was surprised by how much it affected the flight with such a small variation. Thank you for your input before, i might have ruined a bunch of arrows! These were just cabela hunters, id be surprised if a higher quality arrow varied as much with weight and length.

    Usually higher quality arrows are closer in weight on the raw shafts but there will be some variance. Broadheads/field points will vary as well as fletch and wraps. Components will also have some variance so when you add it all together, there can be quite a difference.


    But there again, not that big of a deal.
