I have a Heritage 150 shaft uncut (32.5"), it weighs 353.39 grians. It is 22.9 grams on my triple beam converted 22.9 X 15.432= 353.39 grains. The spec from the mfg is 10 grains per inch and this shaft is 32.5" = 10.87 grains per inch. Am I doing something wrong or is this shaft within the +- what ever their quality control is. Anyone got a bare shaft to measure and compare to my results.

Weigh the entire dozen and see how close they are to each other. The weight differences are far more important than a few grains total. Example.........shoot a group with 125 gr points. Then shoot a group with 150 or 175 grain points. In distances under 20 yards. will notice very little difference in how much they drop. Past 25 yards will notice some difference.

I read some post from Dec 07 and got some answers, it appears that others have got the same results as mine.

I have 18 of the Heritage 150's. 12 of which I ordered from Keystone CS and 6 that I traded for with a fellow Tragganger. I have weighed them on two different sets of scales and I have gotten the same results as you, as have a number of others on here.

Makes it easy for those who want heavier carbons without having to add weight.

Mine were closer to 11gr per inch than the stated 10gr.......

Are you weighing the noc and insert  too?

No just the bare shaft. I kind of have a problem with this, if the MFG is stating a weight (grains per inch) and I make my decission on what MFG to go with based on the advertised weight and the ideal total arrow weight I want and it is not what is advertised than that may be deceptive on their part. I wanted to stay around 10 grains per pound and my total arrow weigth would be more like 12.

To be honest, I hope my carbons are heavier than advertised. The more the merrier!

I have a bunch of Heritage 150s and they weigh anywhere from 10gpi to 10.5gpi. I have had one or two that was near 11gpi. I find on the avereage the ones I have had were just a tad over 10gpi. Shawn

I like a heavier shaft too. So, with a carbon if it says it is suppose to 10gr per inch and they come in at closer to 11gr per inch that is a good thing. It's only one gr. per inch.
