I think Ken Howell's approach has merit: use the big case with a slowish powder and enjoy high--but not highest--speeds at lower pressures. There are certainly limits to such an approach, but the fact that powders are readily available to do this in even a .22-06 makes me wince at the term overbore.
I agree that Ken Howell's approach has merit but sometimes it just does not work out that way.
I am a firm believer in working a load up shooting through a chronograph, as I stated earlier for a long range rifle the most important GOAL is to have a consistent shot to shot load that has a very low standard deviation, some of the new slow burning powders like RL25,Retumbo,VVN170,H1000 etc. help you to achieve this with a case capacity the size of a 22-06. problem is that MOST of the time your pressures are fairly high by the time you reach the GOAL. and backing off the load is counter productive.
