arrow flight problems

preflex · October 04, 2009, 04:23:00 PM

when i shoot my new bow the arrows will fly about 5-10 yards and the nock will drop when come back up also they are shooting about a foot over to the right at 15 yards (as compaired with my other bow) the arrows are easton gamegetters 400 (2117) with 4" vanes and the bow is my martin jaguar takedown 40# @28"
thanks for any advice/help

I think you're so over spined that I don't know where to start. 40# @ 28 should be somewhere in the 1816 or MAYBE 1916 depending on point weight. I don't get good arrow flight out of a 50# bow with 2117s (to stiff). They may work in your 60# bow but they are WAAYYY stiff for 40#.

I agree with moebow. I shot 2117's out of my 55# Archery Traditions longbow at 29 1/2" but really had to bump up the weight on the front end to get them to weaken the spine enough.

In most cases he would overspined big time...the martin jaguar is a compound riser with some recurve limbs ....the riser is cut way past center... i have a feeling this one is going to take some serious trial and error.....

You need your draw weight at the length measured to the back of the bow and then allow 3/4" to the back of the broadhead is the arrow length. For shafts with points above 125 gr. add spine and below subtract. There an interactive chart at the following, give it a try. But read thru to the bottom first.

yeah i had a feeling that they were over spined i bought them for my 60# bow ill have to buy some arrows for the 40# bow next time i have a chance they will probably be the gamegetters in 500 (thats what the chart said with 100gr points from easton i shoot 30" arrows) but it said that i should be shooting the 400 with 125 grain heads which is what i have, that just made me confused even more

im using a rest tho so im not shooting off the shelf if that helpswith the trial and error and is there a way that the rest could be causing the problem maby i need to adjust something i played with it a little b4 i posted this cause the arrows were "fish-tailing" side to side but that was rest alignment

Well there are several issues as i see it.First is to make sure that the spine is right to match the length arrow and weight tip you want to shoot.You can change the spine to a certian point with point weight changes but you are better off starting out with as close as you can to the proper spine. Not sure what rest you are using but you have to make sure that the vanes are clearing things as she goes by.Yes being more center shot will allow a little stiffer spine but if your shooting fingers it is a diffrent ball game.
When you set up your rest and look down the string the string should line up with the center of the limbs and center of riser.If you are right handed it helps to have the tip of the arrow pointing to the left of the string/cener of bow instead of linning up perfect with the string. If using a release it is ok to have everything in perfect allinment.
