Hi Colorado,I would use 150 grainers, Sierra Game Kings boattail is what I use. Great bullet, I push it along right at 3000fps. Great ballistics at this speed. I see no reason to use anything any larger.
I used to think the exact same way until I really studied the ballistics on the 30-06. The 165 grain hold its energy and trajectory just a little longer. At 500 yards they have almost the same impact point but the 165 has over 100 pounds more energy. Some websites list the 165 as flatter at 500 when compared to the 150. When compared to the 180, the 165 shines again. It has very similar energy at 500 yards and is 4 to 5 inches flatter. I'm no expert but the numbers on paper say the 165 is the optimum 30-06 round.
