Well done Kevin.
Glad you're enjoying knocking the little critters over as much as the rest of us do.
Goals are good, they must be challenging and achievable.
Don't worry too much about the score, or the 5 and 10 strings. They will come. You don't need to create additional pressure on yourself.
Just take one shot at a time.
Practice your offhand on paper, 25mtr, 50 mtr, whatever/wherever you can. Even with the airgun at 10mtrs.
Get your position and balance right,
and bring your group size down. There's an immediate goal for you.
If you can shoot an inch group at 25mtrs, then no chicken will be safe !
Get your head around the discipline needed to wait for the shot.
It's all worth it in the long run, and adds to the enjoyment when you exceed your expectations.
Way to go,
I look forward to seeing your progress, and your participation at State and National Championships.
Sean in 'Godzone'.
