I don't think you'll do it with factory loads. Pretty hard to do it at 500 yards with a factory gun also.
500 yards is about the point where the BC of a bullet really starts to matter. If you have a standard twist barrel, you're not going to be able to take advantage of the better long range .22 bullets and will have to make do with 55 - 60 grain bullets. Are you going after paper or critters? Target bullets like Bergers will give you a slight edge on paper but don't do well on varmints.
Stock design, scope mounting and shooting position also become critical at that range. You might want to check out 6BR.com and benchrest Central to see how the F class shooters do it.
