I use a Mathews Solo cam 53# I use Victory VAP 400 spine arrows 27 inch long with 125 grain tungsten point these tune fine at 40 yards they show the spine is slightly week 50mm right impact with bare shaft so I was quiet happy with the result.
I then decided to make up some light arrows for field target & 3D so I bought the same arrow make with 450 spine everything was the same except I put 80 grain points in the arrow.
I expected a arrow that was to stiff as the arrow chart says I require a 500 spine the bare shaft is impacting 150mm right at 20 yards showing it's far to weak
As anybody else had this experience or can explain why this has happened.
Would be good to get some ideas
