Chuck, do you reload at all? Have you done anything to determine your current accuracy of your gun at 100 yards? Basically, anything you can do accuracy-wise at 100 yards will correlate to how accurate you can be farther out. So a 1" group at 100 yards should create a 6" group at 600 yards, as long as you, the shooter, are accurate enough. Sometimes loads can get more accurate out passed 100 yards as well, but this is a good rule of thumb.
My suggestions, other than spending a lot of time on this site reading and asking questions, would be to determine your current accuracy for your rifle if you haven't already done so. Try to get something that will shoot under 1 MOA (1" at 100 yards) and preferably 1/2 MOA. Then, start to stretch it out and practice at longer range as much as you can.
