Ok for those who know more than me.

I shoot a PSE Scorpain , 29 inch draw ,whisker biscuit,4000=55/70Vapors,125gr field point.


Ok when I shoot my field points shoot great love my new bow. Started shooting broad heads Magnus single blade 125gr and they shoot bad They fly all over . Even went to 125gr. first cut single blade shoots real bad too .I want to shoot a single blade broad head for elk .

Ok are the single blades planeing so Iam not getting proper spin or what>?

Things to look for

1) Proper bow tune.Field points are very forgiving of improper tune, broadheads are not, especially big heads like a Magnus.

2) Arrow spine. You may be underspined w/ 125 grain points

3) Make sure you arrows spin straight and the inserts/broadheads spin straight as well

4) Ensure you have enough fletching control. Magnus are a big head requiring big fletching/helical to get good control. Minimum of 4" helical vanes/feathers. 5" would be better.

Tell us how many pounds you are pulling , anything over aboutt 55 and I agree with Jeff , you are probably underspined .

Hey Thanks a bunch!!

I shoot 70lbs. My bow is tuned . I think your right on about fletching/helical to get a good spin thanks alot . I will go that way first.


Thanks!
