I don't shoot at distances like that, but I do know what shoots best in my '06. Your not going to believe it but mine just loves 150 grain Remington Core-Lokt bullets. I use Reloader 19 powder and Winchester LR Primers.
If you can't get the results you want using boat tail bullets, try flat base bullets. Some guns shoot them better.
