Using an off the shelf K31 Swiss rifle (albeit, with hand-loads), Ernie Jimenez reaches out and touches a pink bison target at 2240 yards. Now, there was only four hits in over 80 shots, but the fact that most shots were very near the target is a testament to the marksman.
Arguably, he was on-target for most of them and the natural dispersion of the rifle made him miss, especially when the rounds go trans-sonic.
My hat is off to Mr. Jimenez.
