ORIGINAL: WA Shooter
According to the FOC calculator, I'm around the 10.5 mark with the 5575's.
The arrows would fly great for targets, but I had problems getting BH"s to tune. I could only get the BH's to come within 2" to the right of the FP's at 20 yards. After reading many of the other posts on this board, I am convinced that I should be able to get both of them to be hitting in EXACTLY the same spot.
I haven't tried to tune the 7595's yet, but it did seem that I was just slightly underspined.
I wonder if this has to do with the bow/cam?
My friend is shooting a longer GT 5575 at 74# from his Mighty Mite, and we could get them to tune perfectly. They were hitting exactly the same out to 60 yds.
Well it sounds like your part of the way there. Unless there is something wrong with the arrows it's's not them. If you paper tune at 6,10 and 15 ft. and it is tearing good holes then they should fly right, but even then it just takes some tinkering. Some just tune to the bh and let it go. When this happens vibration, noise and loss of speed is happening even if it's just a small amount. How much can a person get out of a setup? We'll never know if we settle.
