I have always shot arrows that I, as well as others, would deem as "way over spined". I try to have all my bows around 52@29 and have always shot cut short .400's or longer .340's.
Well, per a very trust worthy friends advice, (Big Jim), I swapped to a lighter spine. Jim has that IN HIS OPINION I should try a cut down 500 or a full length 400.
Bare shaft tuning is the only method I have ever had good results with that my broadheads tell me the same thing.
Well, arrow number 1. Is a full length .500, a full 32". I put the insert and tip weight I want in it and go with it.
.500 spine 32",
I shoot, WAY WEAK. Almost miss my target at 10 yard.
I begin trimming.. I get all the way down to 29" and the point is up on the shelf. Still showing weak.
400 spine 32"
Still weak.. trim, weak, trim weak, trim weak.. you get the picture.. exactly same result as with the .500, but it is getting closer and closer to being straight and hitting middle of the target.
.340 spine 31.5"(full length)
Comes off of the bow like an absolute dart. I shoot another one, same result, I fletch an arrow and shoot one with a broadhead.. bare shaft and broadhead shoot the exact same..
It just doesn't make sense to me. How is this my result?
Any insite?
For what its worth, this is the spine I have ALWAYS shot from my bows. But i do not know if it is "correct".
