Mis cut arrows

So I bought some arrows and they were cut 1/4" short. They were measured to the end of the nock instead of the valley. So now I am the owner of a dozen short arrows. They weigh 5-6 gr less than my other arrows (same brand and spine ect)
My question for someone with more experience is;
Can I add 5-6 gr weight to my insert and get them to fly the same as my other arrows? I knows I have had some arrows that had camo on them that weighed 10 gr different and they hit low. I think it would be easy to add some weight to the back of the insert before they were glued in.

I'd suggest you add 5-6 grains to your current arrows and see if you can even tell the difference. Wrap some tape in the back and test it out.

Just didn't want to glue in an insert and have it hit high. I know the other arrows I had weighed 10 gr different just from the camo design painted on and hit low. But I can try and see if more on my current arrows changes it.

I would be more concerned about the change in spine. The weight wouldn't bother me. Might be they won't shoot broadheads the same as your other shafts. But 1/2" of shaft difference in them, if you can detect a difference from the weight shooting them my hats off to you. Probably be 60 yards before you would notice much with a shooting machine.

Haven't tried them. Only past experience with arrows that were 10 gr heavier shooting low. About 5" low at 60. My current arrows weigh 499 gr. So at longer distances they drop some anyway. If the stinking wind ever stops here, I will get out and test one of the current arrows with some added weight (5-6 gr). Just trying to take all the variables. My form is getting better and getting the bow tuned up better than ever. I learned more how to do it myself thanks to the press I built.

It was on the current 499 gr arrows. I think my bow is tuned better now so it may not make as much difference.

5-6 grains shouldn’t show any difference, a lighted nock is 10+ grains heavier than the standard and I’ll shoot 81-82 yards on the tape for 80 yard targets

Probably not much of a difference but you could always cut your old arrows shorter to match.

Yeah, I'm probably not quite good enough yet to tell. Going to give it a try before I worry. The old arrows have the inserts glued in already so can't cut them. Going to set up one of the new ones the same as the old and give it a go. I do have one arrow now from a previous batch that is 3 gr lighter than the others and it is pretty close to them. It is the one that will be high by an inch or so but it may be my imagination.
Thanks for the input.

That didn't have anything to do with the 10gr difference. I can shoot arrows with 25gr difference at 60 yards and they'll slap fletchings.

But I'm wondering how 1/4" of arrow shaft equates to 5-6gr? That means that you're shooting a shaft that weighs 20-24 GPI (grains per inch). And that would equate to a starting weight of 560-672gr even for a 28" arrow........that's before a broadhead, fletching, nock, and insert.

I thought about that but for some reason I thought he said 1/2" short. That made sense to me gpi of 10.8

Cheap scale maybe? Just what it said. Anyway, I dug out those old arrows with the camo paint and re weighed them again and they were more than 10 gr heavier. More like almost 40 gr difference. not sure why the new ones weigh 319 and 317 while the current ones weigh 324 unless my scale is BO. But just going to shoot them and not worry about it too much. Thanks again guys.

It can change the spine. Having two arrows the same length and adding 10 grains probably won't do much I agree, but if you have heavy point weight it could affect accuracy and consistency.

Might not be your original ask, but there was no recourse for the arrows being cut short in the first place?

Bought them on Ebay as they were a good deal? Asked if he would cut them and he said for $.50 an arrow. We agreed and they were cut. When I found that they were 1/4 inch short, I contacted him and the answer was, "that's the way we've always measure to the end of the knock" When I tried to explain that they were not cut to industry or manufacture standards, he said he didn't care and would do nothing. I let it drop and figured I would maybe just add a few gr to the back of my insert before I glued them in as I'm using a Gold Tip 50 gr aluminum insert. I could have disputed it but too much trouble. I use a long arrow anyway so the length won't bother me. If they are going to impact the same as my old arrows, I'm fine with it and have learned a lesson.

I bet the difference of 5-7 grains turns to 2-4 grains once you glue in your inserts, I wouldn’t worry too much about the 1/4”...

I have some old arrows that are the same as my new ones, but about 5/16" shorter and I haven't noticed any change in point of impact.

Yep, just going to shoot them. I did weigh both the old and new ones without inserts to come up with that weight. The 50 gr inserts I use have a threaded hole on the rear of the insert. I was just thinking of filling it with some glue or something to bring them up to about the same as the old.
