Well at least now you are starting to see that luck played a huge roll in those longer shots. I challenge you to go and take those magical Hevi-13 3.5" 2.25oz #5's and shoot at a turkey target taped to the center of a big backer piece of cardboard at a legit 60yds and show us your honest results here. Now you say you have done it already but don't have any 10" counts. I'm from the Show-Me state. That's all I ask. And remember I ask you to be honest. I'll show you the turkey target I would like you to use.

Shoot 3 shots and post them all at 60yds.
God will know if your lying and so will I.
