Sited in at 3in at the range like I was told.Read Deer and Deer Hunter,they said to site in at 2in.Which is correct?

If you are shooting the smaller Florida deer, I would opt for sighting in 2" high at 100yards. Of course it all depends on the weight and velocity of the bullet. Your goal is to get the bullet to the high point of its trajectory at about 3". The idea is to have the bullet go no more than 3" above the line of sight, so that you don't have to hold LOWER on an animal at close range. After the bullet starts falling, you want to note where it will be 3" low. This will be your max point blank range, or the farthest distance where you can hold dead center on a deer's chest and make a clean kill. If it is near the max height, it would hit near the spine, near 3" low, the bullet would hit the heart. For most loads from 150-180 grains in the .30-06, you are going to have a max point blank range of around 270-290 yards with a 2" high sight in at 100 yards. After that point, you would have to start holding slightly higher to compensate for bullet drop. You should have a 3" max bullet height at around 130-160 yards or so depending on the bullet and velocity with a 2" sight in at 100 yards. Of course, don't take these numbers as law. The only way to truly tell where your particular load will be at certain distances in your gun is to shoot at those distances, but I would still sight in 2" high and call it good.

Hope this helps.
