You're ready to rock.I must admit, when I read the thread title I thought "On no! He's cleaning ground squirrels to eat!"
I shot a few rounds at a target at 83 yards and that was a challenge. I bet I wasn't even 50% on those shots. Zeroing at 75 is wayy down the road for me, if ever. Are ground squirrels just that skiddish that you can't get closer? Does the terrain/habitat prevent you from getting closer?
