I'll admit, I don't own a .30-06, I use a 8x57, which is the parent case of .30-06. Felt Recoil is based on rifle design and weight. If your rifle weighs more the felt recoil will be equal with .30-06 compared w/ a lighter .308. There are some "rifles" that because of design tend to be more accurate. Drop at comb on a stock can impact felt recoil w/ the same action in the same caliber. The stock plays an important part, more then most realize. If you look at the evolution of the 1903, it started w/ a strait stock, and evolved into a different stock shape. Why? I've had .308's that could not touch an 8x57 w/ open sights. But when it comes to a purpose built rifle, that changes everything. If you are use to shooting a short action, switching to a long, or Magnum action can seem like a lifetime, and that in itself being forign can effect the way you shoot. Just as pulling the bolt back on a short action when you are use to a long action pulls many shooters off target. Trigger time is what makes accuracy. Knowing your rifle, its' limits, your limits.
