So in my search for heavier arrows, I am still not sure what spine to shoot. Being that my arrows are going to to be under 27". some charts are saying 340 some are saying 400.. In order to get my weight up, the 340 will be easier. I am not going to add inserts or go up in head weight. staying with with 100 gr heads. So should I go with 340 or 400?
What brand ? To know for sure you would have to shoot both. But if I was going to just buy 1 it would be the stiffer. That way if it won't tune you can add weight
My draw length is 27.5. 62 # I went with axis 340. But I can't really tell much difference in my 400's.
Adding weight to the front of your arrow will weaken the spine. If your on the edge now on chart and plan to add weight up front, definitely get the stiffer spine. If you want to weaken the spine more you can cut the arrows longer. My draw is 29" and I cut my last batch of arrows at about 30.5". Plus with a little longer arrow, it adds more weight.
My current arrows are 400 axis and they shoot bullet holes. but they are a mere 385 gr. they are about 2" from my qad rest. so that gives me plenty of room. I could go with 26.75" arrows and likely be just fine with the 400s, and that would put me about 420 gr with the GTs 340 spine and 420 with piledrivers 250. the 350s would get me to 445 gr,
Man you are all about them arrows! At my shop you can buy singles. Play around with em and see what shoots good, build em and go hunt.
I am very particular about arrows. Aome shops around here sell singles but none of the ones around me sell or have in stock either arrows. So when I make a purchase it's going to be either a costly one or the right one...so that's why I am on the fence so much about this one
Many companies, first two that come to mind are Sirius, Grizzlystik all sell smaller sample size groups of arrows to test out.
You can by singles shafts from several brands at www.lancasterarchery.com. For a nominal charge, they can be cut to a specified length. You will have to fletch it yourself as they come bareshaft. I have done this several times when I did not want to buy a half or full dozen arrows.
Where do you buy the CX Piledriver? Are those the PTX small dia? what spine 250/350? It's hard finding these on the web!
I believe you recently went back to shooting 70 lbs? You are a 340 spine all day long with the GT Kinetic. I ran your stats through their calculator with a few different stats. 1. Compound, 70-74 lbs, 27" arrow, 125 grain tip (the kinetic insert is much heavier than a "standard" 12 grain insert, the kinetic ones weigh 24.8 grains, so I threw this in for info), +315 fps (Bow IBO rating). These returned a 300 spine... 2. Compound, 65-69 lbs, 27" arrow, 100 grain tip, +315 IBO, = 340 spine. 3. Compound, 70-74 lbs, 26" arrow, 100 grain tip, +315 IBO = 340 spine. 4. Compound, 65-69 lbs, 26" arrow, 100 grain tip, +315 IBO = 400 spine. A 27" 340 spine arrow will yield 425 grains and 9.7 FOC (assuming 2" Raptor-x vanes are used). 26" 340 spine will yield 415 grains and 9.9 FOC. The GT calculator came out within 3 grains of my actual arrow weight.
thanks mod! Yeh I am thinking the 340's will suit me well. get me up around 415-425 gr and have decent trajectory and good penetration for any deer under 30 yds.
Why switch away from the Axis? IMO its a far superior arrow to anything that CX makes, and probably on par with the GT Kinetics. You can go up to 340's to gain a few grains per inch, and put brass HIT inserts up front and you'll be set.
Because @Vabowman overthinks everything about this LOL...I mean by the 20th thread started on it don't you realize this LOL All in good nature crap giving fun @Vabowman
