Scorch, I agree totally. Long shots are basically "stunts."
The guy with the 338RUM shot five times and his brother about the same at this pig about 1000 yards and never hit it! But, he said, "I almost hit that pig!"
Long range for me on groundhogs is 300 yards and that's too far really - 150 is more like it for consistant kills!
Farthest shot I ever made with my kids watching was about 350 yards, estimated, and I couldn'e hardly see the groundhog for the crosshairs! It was pure luck that I connected - 6MM REM! However I did get two with one shot at about 125 yards - again a 6MM Rem. 87 gr. bullet!
