"With your best field rifle, known range & favorable conditions (good visibility, light to no wind, prone on bi-pods, time on your side); how far do you feel you can hit a 6" circle with your coldbore shot (no sighters) with a 90%+ confidence (you'd be willing to put up a $100 bill on hitting it)"
I have taken a challenge upon my self to try this no matter the conditions. 20 shots on 20 different days!
I will be doing a video documentary on my progress
Today I shot from 587 yards, In very windy conditions.
