LifeNRA Posted July 9, 2005 Report Share Posted July 9, 2005 I learned something today. Different broadheads shoot differently on different arrows! Now I believe that the broadhead needs to be in tune with the arrow! I used only one broadhead and found out that each new arrow flew different! So I match six arrows that I will be hunting with! The broadhead did not come off, but I did take the blades out. Hopefully they will fly the same when I put in new blades! I also learned that I should not shoot more than two arrows with broadheads on! I shaved three arrows fletchings off! Almost did a Robinhood on one, which I had to destroy because the carbon split. What do you all think? Is it a good idea to keep the broadheads with the arrows that flew the best? Quote Link to comment Share on other sites More sharing options...
gowest Posted July 9, 2005 Report Share Posted July 9, 2005 Re: Broadhead and Arrow Tuning? I number my arrows with a permanent felt tip pen on the **** feather (vane) and keep track of which arrows tend to group the best. Once in a while I get a flyer, and when that happens I just put it aside. As credit to the manufacturers, I have fewer and fewer of these flyers in recent years. Because I use fixed blades (G5 Montec's), I also use their practice heads as a means to replicate the sharp broadhead. The numbering system really pays off, especially at longer (40-45 yards) distances where arrow differences are magnified. Give it a try and good luck.

VTbowman Posted July 10, 2005 Report Share Posted July 10, 2005 Re: Broadhead and Arrow Tuning? Lifey- I did some weight testing last fall when I got a grain scale and was extremely shocked to see how much a set of 3 brand new broadheads varied in the same new package. All were labeled 100g heads. 1 was at 91g and the other 2 were well over 110g. This really opened my eyes to mix and matching the heads to the shafts and then weighing the whole thing to get as many arrow/head combos to weight as close as possible. This was the case with 3 different brand mech heads and 2 different fixed blade heads. I found that field tips were very close to one another, as were vanes, so thats was a releif since they are mainly what you use to sight in your bow. However I was upset to find that a 100g broadhead may or may not be 100g... This goes for a finished arrow too. I actually found my Bemans to be closer in weight per dozen the my GTs... As for "flyer" arrows. It could be as simple as too much glue being used on or behind the insert causing slight wobbling or poor flight. Thats been my theory for a while now cause it seems to be the same arrow that goes weird on me. (I number mine too) Just another piece of the puzzle to think of... Good Luck with tuning...

tedicast Posted July 10, 2005 Report Share Posted July 10, 2005 Re: Broadhead and Arrow Tuning? When I get a dozen shafts, we weight them, and pull the closest 6. These are my BH arrows. When it gets time to make up the BH arrows, each arrow has the insert glued in, and is immediately spun to get the broadhead true before the glue sets on the insert. This broadhead stays with this arrow. Doing this All my BH's fly awesome. Quote Link to comment Share on other sites More sharing options...
Guest antlers21 Posted July 10, 2005 Report Share Posted July 10, 2005 Re: Broadhead and Arrow Tuning? Great advise, I think I have some testing to do and some broadhead tuning to do. thanks guys! Quote Link to comment Share on other sites More sharing options...
dg Posted July 10, 2005 Report Share Posted July 10, 2005 Re: Broadhead and Arrow Tuning? It may not be the arrow, but the insert shoved in the front end. I don't think the machining quality of some inserts is that great. BH's and field points are kinda wobbly when screwing in and the shank is not that close tolerance.

Guest coop2564 Posted July 10, 2005 Report Share Posted July 10, 2005 Re: Broadhead and Arrow Tuning? If you have a arrow that wont group try rotating the nock on the arrow more times than not it will change the impact if you are using carbon arrows theres a seam on carbon arrows, that seam can change the virbration of the arrow at launch which will change impact point. I've got arrows that were hitting 5 to 6'' off the group, to tune right in by turning the nock slightly. This shows up more when tuning broadheads.

LifeNRA Posted July 10, 2005 Author Report Share Posted July 10, 2005 Re: Broadhead and Arrow Tuning? Thanks all! I kept the same BH with each arrow that hit the bullseye. Only I took the blades out until I get replacements. There Muzzy's, so hopefully the blades themselves won't change things! Man on man! Did them broadheads chew up my block target! They even shaved a few fletchings off! I guess I must be getting better at grouping the arrows huh? LOL! BTW! The bow is shooting awesome! I now have the broadheads shooting where the field tips are. At 25 yards I can keep six arrows in a three inch group! Look out whitetails here I come! IS IT OCTOBER 1ST YET? LOL!!! Quote Link to comment Share on other sites More sharing options...
PAbowhunter4life Posted July 10, 2005 Report Share Posted July 10, 2005 Re: Broadhead and Arrow Tuning? I second that, a grain scale is a must. I got one for $24 off of archerytalk.com and it's the best $24 I have ever spent. Out of my 12 Gold Tip XT Hunter arrows 10 weighed 306 grains and 2 weighed 308 grains. So I matched all of the 100 grain heads and field points up with the 306 grain arrows and I matched 98 grain heads and field points up with the 308 grain arrows. In the end, every arrow I shoot, in practice or hunting weighs a finished 406 grains. As for broadheads weighing different weights, you'll have that with any company. However, mine only vary 2 grains at the most. The fact that a company let the heads you had out of the facility and didn't reject them when they were QC'd is totally unacceptable IMO.

snapper Posted July 10, 2005 Report Share Posted July 10, 2005 Re: Broadhead and Arrow Tuning? I've never weighed any arrows or broadheads. I use a homemade spin tester. I took a few chunks of wood and attached them in the shape of a U. Got 4 bearings and attached two to each end. Now I can set the arrow in the V's of the bearings and roll (spin) it. With a broadhead on...I will hold a piece of cardboard with a tiny dot on it next to the tip of the broadhead. While spinning the arrow...if the tip wobbles around or away from the dot...I'll try that head in another arrow until I have half dozen or so that are perfectly tuned. They will fly just like my field tips and I can take them on and off and not worry about lining the fleching with the blades. I honestly don't thing 10 grains or so of weight will change impact unless your that good of a shot. I have yet to see a bow shooter that good. Don't get me wrong...it prob. don't help...but I would tend to think your form has alot more to do with accuracy than a few grains of weight differance. If you want broadheads/arrows that are perfectly machined to be exact...you'll more than likely have to pay more for them. Most manufactures have tolerances for their products...if their tolerance for inserts are +/- .003...they prob. could make them +/- .001, but cost more to make and most folks won't pay the extra money for something they can't see.
