I have my field tips hitting where I want and about 30% of time my broadheads hit, the rest fly off to left. Arrows are in the target straight with field tips and BH. By hitting to the left with the BH, is this a sign of a form flaw or not a properly spined arrow?I am a RH shooter.I have done the bareshaft and got pretty close considering that I am new to trad with not so perfect technique.
it's not a form flaw because it's only the b/heads hitting left. sounds like your arrows are stiff. try shooting a group with fletched b/heads and bare field points. i'm assuming you have matched point weights
Could be a little form prob. You might be short drawing the broadheads-- not an uncommon thing.-- which can have varing results -- hitting left could be one of them. Also make sure the broadheads weight the same as field pts. you use. Wt. variances at the tip of your arrow can significant effects. Also some times broadheads can plane, and do strange things. Personally, Iam a big fan of Big Feathers--I use 5 1/2" Bananna cuts-- Another thing you might check is the orientation of the BH to the grain of the shaft. There is hardily ever a pat ans. to these kinds of quest. Too many variables, but nothing you can't solve w/ experimentation. Good luck- you'll get'er figured out.
Thanks for the info
Increase point weight a little at a time untill they come together. You could also try raising your brase hight a little and see if that helps. I know it sounds backwards but raising brace hight will actully weeken the dynamic spine, you can sometimes use this to get that last little bit you need. You will be suprised how much 1/8" makes a deference.
Your arrows are a little bit stiff. If you have good flight but are a little week or stiff the broadheads will show this every time by hitting right or left of the field points.
Righthanded shooter broadheads hitting right arrows week, hitting left arrows stiff.
Try this site, there is a lot of info here so go slow and print it out for quick referance.
