I guess it confers an accuracy advantage to have our sets of arrows closely matched in weight. (The Beman Centershot shafts I am considering ordering advertise that they are accurate to + or - 2 grains. I suppose that is good weight consistency, and that good weight consistency is important to the users.) However, the broadheads that we will mount on our arrows are probably much less consistent that that in weight. If you buy two packs of three broadheads, say, run of the mill 175 grain heads, would you suppose that we would be lucky to get + or - 8-10 grains in weight variation among the six broadheads? That seems to make it irrelevant whether the shafts are closely matched for weight, unless we also weigh the broadheads. And once we weigh the broadheads and find out how extreme the variation is there, do we reprofile and grind down the heavier ones in order to equalize the weights?

I doubt very few on this site would be able to notice a 10grain variance in point weight or shaft weight. I weight everything I shoot, mostly for fun, and I've tried many broadheads and never saw more than a 2-3 gr variance between one pack and another unless I really butchered them trying to them sharp.

Broadhead weights will vary more, depending on how often they are resharpened. With some arrows that may make a difference, but with wood arrows, it is not enough that I can tell. these arrrows are shot from 22 yards, they weigh from 450 grains to 605 grains, from 45 spine to 65 spine, my test arrows, they all flew fine as far as my eyes could see[img]https://i.imgur.com/FwFGF6K.jpg?1[/img]

Oops wrong forum.

I tend to weigh most of them myself, and never seem to see a variance of more than 2 or 3 grains. Maybe I have seen as much as 5 grains on really inexpensive heads i've bought over the years.

My go to broadheads are from VPA and the weight variation is generally around a grain or two. I shoot the 250 grain broadhead on Full Metal Jacket Dangerous Game arrows and the total weight is between 908 and 910 grains.

Well, its good news if we can count on broadhead weight variations of no more than 2 or 3 grains. Based on some anecdotes I had heard, I was expecting more variation. What about you Grizzly broadhead shooters who weigh stuff? 2 or 4 grain weight variations?

The difference in 60gns at 40 yards for me is 3 inches. That was the difference between 2216 and 2219 32 1/2 inches long. That was with sights on my bow in the 70's.

I suppose if ur tune was borderline a heavier head could throw ur tune off.

GLF, 3" difference at 40 yards with a 60 grain difference in arrow weight? I would have guessed more than that, much more. The 2216 is already pretty heavy. That must have been a heavy draw weight bow.

I weigh everything. A long time ago, I bought some new field pts at a local pro shop. Walked back to the range, screwed them on and started shooting. Could tell something was wrong right away. Went back to the desk and had the owner weigh them. I had asked for 125s. These weighed 175. He gave me a funny look, and then dumped the whole bin on the counter top and started weighing every one of them. I think he knew that he had sold them to a lot of people, and I was the first to notice a problem. They must have come mismarked from his supplier.

I weight all my heads too. Some are mighty close. I've had others that varied by as much as 10-15 grains.

Yes I do.

I bought a pack of 200 gr grizzlies. All 6 weighed 185 gr +- 1 gr. They were black and the package said 200 gr.

My Bear Greenies all weigh from 112 to 115 before sharpening. I've weighed (not weighted) a bunch of them over the years and they vary very little. The difference between 125 grain tips and 145 grain tips from the same bow is only a few inches at 50 yards. At hunting ranges you are likely to see little to any difference until you get over 40 grains or so. That ain't gonna happen just through sharpening.

Nobody here is good enough to tell the difference. It's a problem not worth worrying about. Weight tolerance is highly overrated.

What limbwalker said.

Thanks, folks, for your comments. I have heard from respected archers that the importance of arrow straightness tolerances tends to be overrated; and now other respected archers are suggesting that weight tolerances tend to be overrated as well. By a process of elumination, it must be the shaft spine tolerances that are most important.

× 4 y'all can be pretty darn technical for the stick & string crew

"Should we be weighing our broadheads?"

No...traditional archery is supposed to be simple. The difference in weight between two Zwickey's is not going to affect arrow flight to any appreciable degree.

I mean, when you sharpen one are you going to sharpen the rest to be sure they weigh the same?

How precise do you need to be? You are shooting a bow with your hands and without sights. About as imprecise as it gets. 10 or 15 grains either way is not going to make much difference. Especially not to me.

Good one Kevin.... You forgot to mention the importance of drying the broadhead just before the shot it it's raining though.

I shoot stos a lot. The ones I have don't have a screw-on point, so I have to glue them. So I weigh them, but it is amazing how close they end up. I use the ones that spin the best even if they're a little off on weight.

I weigh my broadheads and get my arrows, whether carbon or some other material, as close in weight as possible. Spine, too, of course. I do this for piece of mind more than anything else. I simply know my arrows are well matched.

That being said, neither I, nor anyone else I know, and I've been at this for about 60 years, can shoot/tell a 10-20 difference in arrow weight, and most couldn't decipher a 50 grain or more difference at 20 yards..

Oldnewby, you drew the logical and correct conclusion. Spine trumps weight and straightness for finger shooters, every time.

Spine, weight and straightness - in that order of importance.

I shoot the dozen arrows, pick 6 that I am confident fly well. Spin test the broadheads, shoot the 6 arrows with broadheads to verify they fly well, touch up broadhead and I'm ready to hunt. At one time I weighed and matched everything.

Differences in 25gr won't make much difference in impact if you are just talking weight alone. Extra weight up front makes the arrow weaker. I have Bear Glue on broadheads at home that vary as much as 50grs, low to high. That is significant to arrow tuning affecting arrow flight. Makes me wonder why so many worry about arrow tuning for field points, but a variance in broadhead weight is okay? DANNY

I should have added that was with a 73lb bow and 32" draw. Also it was a measured 40 yards at our club. I was trying to decide whether or not to go to 2219s. The reason for 40 yards ws because that was our max distance at shoots.
