Help with arrow setup for 45# Kanati longbow

[limbshaker]

So after a 2 year break to hopefully forget some bad habits, I'm back at the traditional archery game. Been tuning some arrows and have them flying well but have an odd observation...

My bow is a JK Traditions Kanati 45#@28, and I draw around 27". Shooting GT35/55 Traditional cut to 28.5 BOP. I'm running 175gr field tips with a 1" 2117 footing and getting good flight (so it appears). I can shoot a bareshaft at 25 yards and it sticks in straight and within just a few inches of my fletched arrows.

According to the Dynamic Calculator, and from seeing what others are shooting, these should be way stiff. When I put a 200+gr tip, the arrow visibly noodles around but still groups decent. I can even drop down to a 145gr point and still fly straight.

I was shooting the same setup with shafts at 30.5 BOP and 175gr heads and couldn't hit squat. So I started playing around and it's like a switch flipped when I put a 100gr head on, they shot lights out. So my logic was to cut them down, and add more point weight to make a nice high FOC setup.

What gives? Is it me? Is it mislabeled arrows? Am I just lucky?

I shot woods last time around, and had them flying great in no time. They have always been a breeze to tune for me.

Just wondering if you guys have ran into similar. Thanks for sharing any thoughts!

I can't tell you what is going on,sometimes this stuff defies logic, but I shoot a 48#@28" Kanati also drawn 27". 600 29.5" BOP with 145 gr. Fly like lasers.

Your logic is sound, likely just took too big a step at one time, i.e., going from 30.5 inches and 100 grains to 28.5 inches and 175 grain heads.

If the first combination shoots lights out, I'm thinking a 150 grain point would work better with the shorter arrows. Regardless, the 35/55s should work.  just may need to play with the length/weight variables a bit more.  Good luck.

1535 gold tip full length with 125 point shoot great from my 45# longbow

Two kanatis both 45@26. Gold tip 35/55 cut at 27" with 100 grain inserts and 150 heads. 3 5" feathers full helical. Shoot like darts

Thanks for the info guys. Something must be a little weird with my setup or technique (highly likely) or both        

At the current configuration they have a dynamic spine of around 60#.

My first go round setup was about 56# dynamic.

Most guys, and Bucky above (Thank you for sharing your setup) shoot more around 48-55# dynamic spine.

As long as they are flying alright I aint complaining! I was just a little bumfuzzled as to what was up. This bow may just be a funky shooter. I like it though.

Thanks again!

Whats your brace and nock height? You shoot split or 3 under?

[limbshaker]
