I am really leaning towards the 30-06 version, with the extra barrel length, it should have more than enough powder capacity to drive the heavier bullets the distance I want. While years ago I had big dreams of being a long range hunter, reality is i don't get enough time to send the rounds down range to be confident at much more than 500 yards, and most of my shots at game have been less than 300. I have a 300 Win Mag that I have hunted Alaska and New Mexico with that has served me well over the last 17 years, but the rounds count is stacking up, and being a fairly light rifle, it isn't as much fun to shoot from the bench these days. Just kicking around ideas, I load for both, the vast majority of my 30 caliber projectiles are 200gr or heavier. Originally I was just going to put a little more optic on my 300 (wears a VX III in 2.5-8x36 now) and shoot until the barrel needs replacing, the '06 is a Weatherby Vanguard I picked up for less than $300 for my Son who is serving in the Navy, as soon as he gets settled, I will be without an '06. I have some deciding to do.
