Just weighed my shafts with a new digital scale. Guess what? My broadheads are 6 grns. heavier than my points. The 100 thunder heads are 106, all of them. The points are exactly 100. Wonder why your heads drop below your points? The 85 grn. tunderheads are better, they are 86.
For those of you that have to know "why", get a scale.
Any body weigh some heads before for consistency? Who's the best?
It is good to weigh your arrows and components but adding six grains to the arrow wouldn't make an inch of differance at 50 yards. Especially with todays fast bows.
If they all weigh 106 grains then be happy. I've seen some broadheads weigh anywhere from about 93 grains as a low to 107 grains as a high. Of course these were cheap-o broadheads but.....
I'd be willing to bet you dollars to donuts that there is more than a 6 grain variance between your finished arrows with nothing screwed into the tips. Unless you weigh each vane, nock, insert, use exacting ammounts of glue and then match the heavier components with the lighter shafts and vise versa it isn't uncommon to see arrows that differ as much as 15 grains or more in a dozen after they are all finished.

I agree with bigbulls on this one. I do a lot of testing and playing with a lot of stuff. In my experience if you can shoot well enough to see a difference of 6gr anywhere within 50 yards then you should be shooting for a living and not holding a job.
In my case I often shoot 82gr Nibbs all summer long and change to 75gr broadheads for hunting. There may be a change in impact point but not within at least 35 yards.
Now that you have your scale I suggest that you weigh every component that makes up a completed arrow. I've seen a 7gr spread in the same batch of 4" vanes.

Yep. I just thought the heads should be much better. 6 grns. is the difference between great shafts and ordinary ones. That say's something for the difference. Weighed mine and they are, built, within 1, except for the broadheads. GT pro's, duravanes. I did notice a difference in the nocks. GT's nocks with the screw are 15 and without 12.
Just a need to know I guess (a need to know it's not me mostly) and there's not much else to do with the bow and arrow this time of year. I suspected that in the vanes. It was one of the reason's that made me buy the scale. Gander Mnt. weighed some 4" vanes @ 4 grns. I knew it was time. The guy was blind in one eye and couldn't see out of the other and the scale wasn't digital, but he worked it for several minutes and after coming up from the floor anounced, they were without a doubt, 4grns., for sure. It's kind of funny now.
I doubt anyone on this site, or mostly anywhere for that matter, can tell the difference in impact over 6 grains, that would be like 1 fps tops.
However, putting an identicle weight BH will change the flight characteristics a bit. Puts more weight out front since the BH is 1-2 inches long and a FP is about 1/2 inch long. Also makes tunign more critical.
If you're honestly worried about it, I have some field points that I will sell you. They are 106 grains on the nose.
Only $5.00 per field point.
Just kidding...Im gonna have to agree with the others though....6 grains, while upsetting to know, is actually very little in the world of arrow tolerances. You arent going to notice a difference.
If it makes you feel better, find the heavier nocks, and put them on the bh arrows, and the lighter nocks on the fp arrows.
Broad head and field point hits.
It's kind of funny now.
