I think we all need a little more practice on range estimation. For those of you shooting 500 yards I would like to know where you're aiming. As a former Marine marksmanship instructor I am quite accustomed to shooting 500 yards with rifled sights. While I can hold a 3 inch group at 200 yards it's more like 30 inches at 500. Of course you raise the rear sight aperature about 1/2 inch to make a 500 yard shot or else you'd be off about 6 ft. Not to mention a silhoute target looks like a toothpick at that range. So for all of you shooting your scoped rifles are we making these sight adjustments or just aiming 6 ft. off the animals back?

ps. The one that said he can shoot squirrels at 400, the Marines are looking for a few good snipers.
