To each his own, but for me the 06' with 200 grain partitions traveling at 2600 fps is a formidable package, and I can do a better job of hitting what I'm aiming for when I don't exceed that amount of recoil.
I've seen people shoot much bigger rounds with the same ease and demonstrate good marksmanship, but the normal guy starts developing some bad habits. (as I would)
So the ought-six is my logical "big rifle".
My step down rifles are a model 94 win 30-30, and a 6.5x55 swede.
