I have a friend that likes to brag about killing deer at 500-600yds with his 30-06 742. Finally one day I had enough and took him to the range and asked him to tell me how far the targets were, he was off by 100-200yds at the least then I told him to shoot at the 600yd gong, it was bigger than a deer so he should have no problem hitting it, well after 10 shots he did not ring it one time. I told him that I would help him make those shots and really kill deer at 500yds but he would rather brag about shooting deer at 100 and calling it 500.
