I agree with Jeff,you have to rule out contact and timing issues.

These arrows are stiff by quite a bit (However,this is not your main issue) you FIRST need arrows that will fly consistant with field points before you even think about broadheads.


You are in need of about a .700 spine.Easton has a Redline shaft that is a .690 and if you cut them to 25" raw shaft,they will be right on the money for 48#'s.Put some good helical feathers on there and all should tune well with broadheads.


If you have time to head southwest a couple hours,I could help you out.
