I am new to reloading also, but I have learned a lot in a short period. From what I have learned is that factory ammo is loaded to a OAL that is pretty much safe and functions in all firearms, but doesn't necessarily give the best accuracy it can because every firearm is different in the amount of "jump" to the rifle lands that it requires for best accuracy. You could seat the bullet where it actually touches the rifle lands, but then that will create excess pressure that could become dangerous if you didn't back down on the powder charge. In the Hornady reloading manual they suggest seating the bullet from .020-.030 off the rifle lands to give it just enough "bullet jump" for best accuracy. There is a lot to bullet seating depth and is probably one of the biggest things a re loader can do to improve accuracy.
