Tuning two blade broad heads

[TreednNC]

Ok so I was short on time the other day, made some repairs to my bow saturday, got it dialed in to 30yds, in a hurry, and put my Spitfires in and went hunting and took a descent 8pter that evening.....

BUT....those arent the heads I WANT to shoot. I just bought some 2 blade Magnus Stingers. Theyre tough and easy to sharpen, but dont seem to want to be consistant with me. Havent had time to shoot them since getting some repairs madeon the bow, but just know 2 fly one way compared to the field point and and one is dead on.

What are some basics in tuning a two blade fixed head?? I can tune a 3blade like it's nobodys buisness......

So...

Alignemt with fletching?
Blade at an angle? Blade vertical? Blade horizontal?
Who the heck cares.....screw it in and hope it hits brown?....J/k!!

Any advise would be much appreciated

Feather fletch, helical.3-4" or 4-3" should do the trick. Trad style heads seem to appreciate a little more FOC, as well.

You need a good helical fletch or at least some offset. The bow needs to be tuned for proper arrow flight and each arrow spin tested to ensure there is no wobble in the broadhead. Mechanicals tend to be much more forgiving and you can get away with not following these steps and still get good flight. Not so with longer larger traditionaly styled fixed blades.

ive heard that 2 blade heads like to be aligned with the string.....but i dont know...never shot them...maybe post this on the Traditional forum....more of those guys have expirience with 2blade heads than most compound shooters...

Didnt think about that, as I shoot a compound myself.

I shoot a compound and two blade heads (muzzy phantoms, no bleeders) and the above quotes just about cover it. Start with a well tuned bow, an arrow that is spined correctly and 12+% FOC (my preference) and it should tune and shoot with FP's. You may not want to use 2 blade BH's if your going to be shooting over 300 FPS. I have heard the higher speeds are not friendly with larger surface BH's like a 2 blade would be.

I have not found that to be the case. It looks cooler with the BH alignedto the string but the arrow flys the same regardless.

2 hitting bad and one hitting good, makes me want to think there might be an issue with the arrows too. Maybe not squared?

Matt.

What arrows do you have plus bow, poundage, draw lenght and what fletching do you have?

Did you spin test them?

Spin test them, work on form. Same as a 3 blade. Maybe less forgiving due to the design.
