Yeah, and tight groups at short distances don't mean that the rifle, or your ability, should justify taking the 300+ yard shot. If you cannot sight a rifle in off of a bench so that it hits the target every time at 100 yards or 200 yards, then you shouldn't be shooting at game around 400 yards.

Now, if you zero a rifle in at 50 yards, and the group is an inch (for arguments sake), shouldn't that equate to a two inch group at 100 yards and a four inch group at 200 yards and an 8 inch group at 400 yards. All of a sudden, what looked like a good group at 1" at 50 yards could turn out to be not so good at 400 yards.

Best case scenario, if you have the land/range length, site the gun in at 50 and then practice with it out at 100 yards, 200 yards, 300 yards, and 400 yards so you will know whether or not you can make those shots.

Me, I site my guns in for 1" high at 100 yards. I think Rocky Raab or somebody else on here has said that 1" high at 150 yards is dead on at 300 with very minimal gain between zero and 150 yards. If I had a range to shoot on that was 300 yards, I would test that theory. Heck, I would like to have a range to shoot at that has 150 yards, but might be joining one soon.
