RE: Tuning question
I'd take your bow to a local shop. Even though most are pretty busy right now, you'll probably only have to wait a day or 2 for it.
I killed my first few archery season deer with muzzy's. They are a solid head, but with each pack I bought, at least 2 out of the 6 were flyers, and would not group, even with a paper tuned bow. I could screw the flyers on an arrow, spin them on my finger, and be able to tell they weren't in line with the shaft. I figured if I am paying for 6 heads, I should be able to shoot all 6 with no problems. From that point on, I didn't buy muzzy's again. That being said, they killed every deer I shot with them, no problem.
Do you have your bow with you in State College? I can send you in the right direction of a good shop. Also, let me know if you want to shoot sometime.
