Ive got an older scale(the balancing type) Its pretty precise, my pop used it for weighing bullets. Anyway i'll check my head weights when i get home. You peaked my curiosity.

In the past I have weighed heads, I weighed arrows, feathers, vanes, washers, peeps, etc,...

I think you will find that like the rest of our world nothing is perfect. There is going to be a variance in the specs regardless of what the stated weight is. What I look for is consistency in those variances. Some companies are better than others.

I use one to weigh my target points. Even with the ones that are supposed to have tight tollerances, there is a 2 to 3 grain difference.

You will also be surprised at the difference in the weight of vanes. The 3" vanetecs have a range of 6.6 grains to 7.4 grains. QuickSpins were even worse. Even feathers have similar % variations, but because they are so light the actual weight variation is much less.

I've been told to make sure that the points all weigh exactly the same and to make up any variation in the back end of the arrow. The theory is that a lighter shaft has a weaker spine than a heavier shaft and the addedweight at the back will compensate for this. I haven't been able to prove this since I'm not quite that consistent, but is seems logical.

Anyone else do this?

how much will a a few grains REALLY matter in real life typical 40yd or less hunting range though?? im new to archery so i dont know...maybe it does make a huge diffrence...maybe you guys are being a bit finicky! lol....i know mannnnnny reloaders do it and even muzzleloader shooters that do weigh stuff also....when the matter of hairs of an inch matter id say go for it....but for the average hunter will it make a huge diffrence??

LOL mauser... That's why I started my post the way I did, saying I'll probably be like the guy who was always perfectly happy shooting a particular bow until the one day he sees his arrow flash through a chrono! [8D]

You're right; I don't expect much difference -- other than confidence. That alone will help tremendously for peace of mind while on stand, knowing that everything is matched as precisely as I can get it. And after havind done this for a little bit, I can tell you confidence is one of the most important things you can have going for you, whether it be confidence in your scouting, stand placement, yardage estimation, shooting ability,or equipment.

Most of us would never know the difference in p.o.i.

It would be tough to know where to exactly draw the line for the average shooter. There are so many other variables that affect arrow flight (grip, the release, stance, wind, etc.) I dare say that if one shot an arrow on the stiff side of the spine chart, the averagehunter would have a hard time telling the difference between a 100 grain head and a 125 grain head.

I have weighed several heads and there are only a few that actually weigh what they are suppose to.

Muzzies are almost always different than stated and also inconsistant.

Most all mechanicals are off and inconsistant.

THe most consistant field tips I have found are Gold Tips. Every one I have weighed all weigh as advertised.

I too have found this to be true. Every single ST I have put on the scale all weighed 125 grains on the nose.

I have noticed this too. If i remember right, most of my 100 grain spitfires showed 103 grains.

I remember it too with NAP Thunderheads. Don't get me wrong they are great heads, but they are way heavier than they appear. I read (on here a while back) where someone weighed Thunderheads on a reloading scale. The 100 grain Thunderhead was actually 106, and the 125 grain was around 130.

I loved shooting Thunderheads, but always had to keep in mind, that 1/2" or so more drop compared to regular field tips and other broadheads. Like I said, Thunderheads are great, fly great, perform great, but they just fly a little lower than some.

Greg, I have the same scale from BPS and noticed a difference in my heads last season. They all grouped well so I didn't really worry about it.
I also noticed that my 3 Slick Tricks weighed 100, 100 and 101. My Razorsharks were all over the place between 97 and 103. But what is +/- 3 grains going to affect under 40 yards? I played around with components and my hunting arrows are all within 3 grains of one another. I can see where pro target shooters need more consistancy shooting out to 100 yards.
