Set up:
Bear approach single cam 60#(not measured just maxed out limbs)
30.5 inch draw
Easton powerflights 340 spine 9.3 gpi
Drop away rest
Trophy ridge react one pro sight

The problem:
Great groups out to 30 (for how long ive been at it)
After 30 very inconsistent arrow flight.
Current sight and old one both bottomed out to get even close to proper elevation set.
The react should let me shoot to 100m with my advertised speed. Aiming high with the sight at 100 the arrows wont go out past 70m.

My theory:
Something is slowing my arrows down.
Im hoping its garbage bargain basement arrows.
Am i wrong
