I used 3031 in the .30-06 for several years after I began reloading in the early 70's. I don't remember the exact loading, but it was in the modest range using data from the Lyman Handbook of the time and the Sierra 165 grain HPBT fired from a Remington 760.

Groups at 100 yards were a little under an inch from the trombone rifle, something I have not been able to achieve since with a Ruger 77, but, oh well.
