Was in northern Mi. Sun - Tues. Didn't get a deer. So windy, trees were falling, and temps in the single digits. Didn't see one deer. On the bright side the breech plug Ron Laughlin made me, lit BH209 with ease. Ambient temp was 2°F. I believe it helped with accuracy, as before I had some issues. Punched the center at 113 measured yards on a clean barrel, off shooting sticks. I'll know more when I can get to the range and fire more, but for now very pleased. Good work Ron.
