From my experience with a .308 Rossi, you really gotta let them cool down. .30 - `06 would be even more so. fire 3 rounds, and then let it cool to cold. Read the instructions for adjusting your scope ( if you have them. ) At 50 yards one click could be and eighth of an inch, could be half, depends on the scope. But first and foremost, let it cool. If I try to keep firing after 3 shots, it`s all over the shop like a mad womans poop.
Also, my .308 kicks like hell, whats an `06 like?? It`d be stout, eh..
