Here's my situtation:

I'm currently shooting Easton XX78 Super Slam 2314 with 4" feathers and RH. I'm able to shoot good groups but my arrows dance on occasion. Also I can't get my field tips and broadheads to fly the same so I adjusted my sights to the broadheads.

I considered that maybe I need to switch arrows, so when I looked at the Easton chart, I'm reading that I should be shooting arrows in group J. Am I correct? Maybe the arrow guy at the pro shop had a dyslexic moment and meant to give me 2413?

I'm shooting a Bowtech Liberty
28", 70# and 125gr broadheads

If Group Jis correct there are 4 sizes to choose from.
2512, 2413, 2315, 2219

Which would be best to clear up the dancing problem and possibly bring my field tips and broadheads in line? Also best for deer hunting.

I appreciate any help. This is beyond my experience level.

Thanks

I ran the numbers through OT2 and a 2413 arrow at 28 inches ran you in the middle of the green

Maybe one turn off the limbs would help. It's cheaper than new arrows.

So is this really a trial and error process? In this case adjust the bow to the arrow which would work if the weight was less.

Adjusting the bow to the arrow is much easier than playing with different spined arrows, different fletching and all that other crap. That's why compound bows have limb bolts. And yes, there is some trial and error involved--it's called tuning. It's often more involved with aluminum arrows because they don't fit such a varied draw weight range as carbons.

Ok , I reran the numbers through OT2 and using the same arrows your have at 28 inches long, Is that how long your arrows are, and using the 125 grain heads , if you went down to 67 lbs you would be in the middle of the green . 66 lbs put you slightly on the heavy spine side but for broadheads would be fine. Most people dont want to drop their draw weight for fear of losing too much speed.

Well, I bought 2413 arrows. My first shot with the field tips was dead centerand the arrow flew perfect. I tried the broadheads with the same result. No noise and no fishtailing. I wish I would have tried this earlier.

Thanks for the input.

Sounds like the bow needs to be tuned to the setup.
