attempting high foc with new bow

[DK]

#2457

Alright,

I am shooting a new javaman elkheart. 58# @31.5″. This bow is pretty much identical to my old elkheart it is two inches longer and one pound heavier. My older elkheart shoots a 300 spine beman ics bowhunter full length 32.32″ with 350 up front. My new bow is shooting the same arrow and grizzly BH all to the left with very poor arrow flight. Am I to stiff. I don’t get it. Any advise would be appreciated any other long draw guys out there.

Thanks

Too many variables unknown to comment.

Go to Tuff Head site. Read and print out Troy’s Tuning for EFOC on t hat site. Explains it all better’n us can!

Doc,

I agree that is a great source for tuning an arrow but I cant cut my arrows down at all because my draw length is 31.5. Is there anyone out there who draws over 30″ and is in the 55#-60# range. And what is your set up. Should I switch to 340’s? I dont want to because I have a feeling they will be to weak with 350-400 up front.

Thanks

Yup. Long draws and carbons are a headache… Friend did an extension, sent you a PM… using field point ground to 5* taper…then glued on a wood arrow point to that…gave him another 1″ to play with, but more weight up front! Didn’t need to have inserts in his BH’s though…they glued onto his tapered field point extensions!

As for recommending spine…my, my… seems to me, and I don’t shoot TONS of bows like some do, but in my experience, I’ve shot a dozen different bows, all the same draw weight at my draw length and they all SHOT different…!

Draw force curve, efficiency of the design, lateral and vertical limb stability of the design…all required slightly or vastly different arrows.

My Bigfoot LB came in UNDER my other bows by 2# and I had to go from 400 to 340’s to harness the extra energy Kirk KEEPS in his limbs and imparts to the arrow…where it’s somehow lost in other designs…

Go figure!:shock:

Thanks Doc,

I will check out the PM. I guess I will just have to try 340’s with all different heads. I am ordering a SBD string, that might speed it up and weaken it a little though.

Thanks again,

DK
