Here i go again...Carbons (Update #2) a blow by blow of trying to tune a carbon

[wtpops]

I have never really had good luck with carbons, with my draw length 31" and the need for a 32" arrow and my draw weight 59# @ 31" I always seem to fall right in between arrow spines to where my arrow is to light with the lighter spine or to heavy with the stiffer spine so I gave up on them about 3 years ago.

Well the bug bit me again and I decided to give it one more try. I never did try the skinny ones so I’m going to give the MFX Classic 340 a try. When all said a done I’m hoping for an arrow around 600 grains. The MFX is going to sport the VPA terminator in 175 or 200 grain with a 75 or 50 grain hit insert. If it works            I should have a killer arrow.

One of these day I will find that one arrow that will just make me smile. Wish me luck from past experience I’m going to need it.

Just foot it with a piece of re-bar.Good luck !

I'm in the same boat. I am shooting full length 7795s that nock right with bare shafts and 175 gr. field points. With 7 inches of crest wrap and four 4" shields my arrows weigh 578 right now, so 200 grains (just ordered 200s and 250s this morning) would put me right at 603 grains.

pops, im shooting 59lb at 31# with my widow and im shooting Full metal jackets 300 spine 32" long and they bare shaft great for me with a 75gr. brass insert and 125 field point.

I think you'll like those arrows. You just can't beat a Beman MFX Classic!

[Oregon Okie]

I'm shooting 54 @ 31
300 spine with 220 up front including insert. that bow is cut a little past center...
590 grains or so.
yeah, 31 inch draw and arrow finding is not the funnest game.

[Bowwild]

I doubt I will ever shoot another arrow now that I've "discovered" Beman MFX.

I shoot my age - 10 so I need only 600 or 500 spines with my arrows ending up at 414-500 depending upon which way I go. I long (a little) for the days when I shot my age + 10 by the way.

Pops, the mfx classic is 11.2 gpi, the axis and beaman bone collector are 9.5 gpi if your looking at weight. Easton's web site lets you print a $10 mail in rebate for a dozen, $5 for 6.

Pops, I shoot 58-62@31 with all my bows and with some bows I find the CX Heritage will fit some of the spine gaps as they are spined a little different than the typical 300,340,400, etc...  They are some of the heavier carbon shafts as well.

Yup it can be a pain, I’m not looking a gift horse in the mouth, but I like to tinker and am envious of the guys with shorter draws that can play with a lot of arrows to make what they want and we are stuck with what will work weather it’s what we want or not, don’t get me wrong when I go out in the field I am very happy with a set up that works just the tinker side of me can’t play like I want to  

[ishiwannabe]

I switched to the beemans last year. I shoot 56@28. Im shooting 340's, 75 grain insert, cut to 31.5" and 150 grain head. They seem to fly great, but I had to put off fine tuning until I heal.
GREAT arrows. I was impressed with CE 150's. I only broke one at the Muzzy(arrow eating stump shoot). My buddy didnt even ding one of his beemans, and that is when I decided the next arrows I tried would be mfx. So far very happy.....except for the amount of strain it take to remove them from the foam targets.  :D

[wtpops]

Udate..... recived my MFX 340, again to light when tunned. Ordered some Axis 300, just recived those and again to heavy when tuned. so i have some good tradgangers sending me some 2016 cutoffs that i will try footing the MFX 340's with to try to stiffin them up. This should allow me the keep the weight i need up front. I will use the 75 grain HIT insert ( i really like these by the way) and a 175 grain tip and will adjust the footing lenght untill it tunes. Should have the cutoffs any time. I think this will work,      Again wish me luck unless you are in the market for some MFX or Axis then dont

wtpops, the footing will increase the diameter of the shaft at the side plate possibly making them act stiffer. Adding more weight beyond that of the footing might take care of that and your lightness problem.

I plan on starting out with a 3" footing this will reach back 1" past the incert and as far as dynamic spine will in effect shorten the shaft by 1" which should stiffin the shaft quite a bit. I will most likly end with a footing a bit shorter than that, im guessing some where around 2.75 to 2.5 inches but will start with 3" and assumeing to stiff at this lenght will cut the footing shorter untill it comes into tune.

I would try the carbon express heritage series 150 shafts or an arrow dynamics shaft.

The 150 is way to week for my set up remember i need a 32" arrow. Im like right in between a .340 and .300 deflection, i can get both of these to tune but the 340 ends up way to light for my liking and the 300 ends up way to heavy. i think footing the 340 to make it stiffer might just solve this. Thank you for the input

[katman]

wtpops, can you add more fletch or perhaps a cap wrap to stiffen the 340's?

[awbowman]

Try Hertitage 250s and add weight untill you get there.  It will happen

The 250 has a .373 deflection and will be way to week i am between a .340 and .300

Pops, keep us posted on your findings.  I always like to see what other long draw shooters get for results, especially because I have a new bow coming.  It will be 58# at my 31" draw.  I am planning on going with the CX Heritage 350 which are .320 spine and 12GPI.  I've used them on my cut to or past center bows at around 60# and ended up with arrows 32-33" long with 150-225 up front depending on the bow.
