You guys kill me! How about I take out the 6.5 this weekend and show you what you need.....again.
Roy, on the 6.5-06, I'd skip the 120's and run the 140's out of it. You should be able to get 3150 or so with the 140's and at 700yds it will be flatter than the 120's. There's definately plenty of power for deer (and probably elk but I haven't tested my theory yet) that far away. If you have the supersniper, you'll be good for elevation to about 1200 yds without having a tapered base. I'm running them at 2940 out of my 28" barrel and accuracy is unbelievable-3/4" at 300yds and one day for fun, I shot 3 push pins in a row off of sand bags at 100yds.
You guys keep playing...maybe I'll break down and build something else, but for right now, the 6.5x284 is still king of the "rock". (although I've gotta admit the impact of a 240smk out of the tommy at 550yds on a deer is impressive
)
