Broadhead tuning problems...

I've never bare shaft or paper tuned to be honest, I've just always thought "if it flies well with a broadhead then I'm all set".

Looks like I'll give some 500's a try and start with bare shafting them.

Thanks for the help!

You are correct,if it flies well with a broadhead,you are set.Bare shafting just gets you there without having to try a bunch of different broadheads.You can actually tune with just broadheads but I just find it simpler,with a screw in point system,to bareshaft tune by changing point weights,then come up with a broadhead that works.

 If that doesn't help drop you spine (or really raise your point weight) I have a stalker fxt wolverine 52@27 and I shoot 29inch (500) gt 3555trads with 50grn insert and 175-200 grn points bare shaft tuned.
Watch this vid he talks some on strike plate tuning
     

Thanks for posting this that is a fantastic video, never seen that before. Definitely going to take my time and tune them right now.

yup too stiff an arrow for that setup

I ran your setup through Stu Millers calculator and It said 200-250 grain tips or more might work(but stu is always to stiff for me) 100 grain inserts with your points might work.

I run a fairly similar set up just 2 pounds less and a little shorter draw. I shoot victory 400s cut 30.5 inches and shoot 250 grain points.  My bow is cut 1/8 shy of center.

I know it's not apples to apples but I bet those might be a bit stiff.

Yes it may be the arrow spine . My question is did you spin test your heads ? I find screw in head incerts can get bent and cause bad arrow accuracy .

Ken Beck of Black Widow Bows has an excellent tuning video on YouTube showing everything you need to do to get your arrows flying perfectly.
